PULSAR TELOS XG50 Manual

Telos thermal imaging monoculars are designed for use both at night-time and during the day and provide exceptional image quality even in adverse weather conditions (fog, smog, rain) and beyond obstacles like branches, tall grass, dense foliage, etc. known to hinder target detection.

Unlike night-vision devices based on electron-optical converters, thermal imaging devices do not need an external light source and are resistant to bright light.

Telos thermal imagers are designed for various applications including hunting, observation, security, terrain orientation, search and rescue operations, etc.

Battery Pack

• Quick Change Li-Ion Battery Pack LPS7i
• Charging from USB Power Bank
• Quick-Charge power delivery​

• It is not recommended to charge the battery with the USB cable and wireless charger at the same time. This will not increase the charge rate and may damage the battery.
• Use the USB Type-C cable and power adapter supplied with the device (or purchased separately) to charge the LPS 7i batteries.
• Follow the safety precautions described in its Manual when using the wireless charger.
• Do not place any foreign objects between the battery and wireless charger platform.
• Do not charge the battery immediately after bringing it from cold to warm. Wait at least 30 minutes for the battery to warm up.
• Do not leave the battery unattended while charging.
• Do not use the power adapter and wireless charger if they have been modified or damaged.
• Do not leave the battery plugged in after charging is complete.
• Do not expose the battery to high temperatures and naked flame.
• Do not use the battery as a power source for devices that do not support LPS 7i batteries.
• Do not disassemble or deform the battery.
• Do not drop or strike the battery.
• Do not submerge the battery.
• Keep the battery out of the reach of children.

• The battery should be partially charged (50 to 80 %) for long-term storage.
• Charge at an ambient temperature of 0°C to +35°C (32°F to 95°F) or the lifespan of the battery will decrease significantly.
• Using the battery at sub 0°C (<32°F) ambient temperature decreases battery capacity. This is normal and not a defect.
• Using the battery at temperatures outside the range of -25°C to +50°C (-13°F to 122°F) may reduce battery life.
• The battery is short-circuit protected. Any situation that may cause short-circuiting should be avoided.

The Telos thermal imager comes with an LPS7i rechargeable Lithium-ion battery. LPS7i batteries support USB Power Delivery fast charging technology when using a standard charging set (USB Type-C cable, power adapter). Before first use, make sure the battery is fully charged. LPS 7i batteries also support wireless charging.

The icon in the status bar will flash when the battery is low. The battery needs to be charged.

Option 1. USB Charging 

1. Install the LPS7i battery in the battery compartment of the device.
2. Connect the USB cable (20) to the USB Type-C connector (16) of the device.

	Battery is full

Option 2. Charging the battery via USB

1. Remove the protective cover (8).
2. Connect the plug of the USB Type-C cable (20) to the USB Type-C connector (18) of the battery.
3. For fast charging, connect the second end of the USB Type-C cable (20) to the Type-C connector of the power adapter (21) by removing the Type-A adapter from the plug. When connected to a computer or a Type-A power adapter, the battery will charge at normal speed.
4. Plug the power adapter (21) into a 100-240 V socket.
5. LED (19) will display battery charge level (see Table).

LED indication	Battery charge status

2. Turn on the wireless charger according to its instruction manual.
3. LED (19) will display battery charge level (see Table).

* Third party-purchasing. The LPS7i battery works with all QI standard wireless chargers.

Note: Charging with a USB cable is significantly faster than using a wireless charger.

1. Install the cover (7) on the LPS7i battery (6).

2. Insert the battery (6) into the battery compartment (5) until you hear a click. The battery contacts must face the top of the device (see diagram).

3. To remove the battery (6), slide the switch (A) on the cover (7) to the left .

Power can be supplied from an external source such as a 5 V or 9 V power bank.

1. Connect the external power source to the USB Type-C connector (16) on the device.
2. The device will switch to draw power from the external source while the LPS7i battery is gradually recharged.
3. A battery icon  will appear on the display showing the percentage-charged level.
4. An icon  will be displayed when the device is powered by an external power source and the LPS7i battery is not connected.
5. The device automatically switches to the LPS7i battery when the external power supply is disconnected.

Attention! Charging LPS7i batteries from an external source at temperatures below 0°C (<32°F) can reduce battery life. When using external power, connect the power bank to the device only after it has been turned on and working (warming) for at least several minutes.

  .
• The Wi-Fi function will turn off automatically if there is not enough battery power for Wi-Fi. To use the Wi-Fi function again, you need to charge the battery.

Telos thermal imagers are equipped with a stadiametric rangefinder which allows the user to determine the approximate distance to an object of a known size with reasonable accuracy.

1. To select the Stadiametric Rangefinder function, enter the Quick Menu by briefly pressing the MENU (11) button.
2. Press the MENU (11) button briefly to select the icon .
3. You will see on the display: measurement bars, icons of three reference objects and respective distances for the three objects.
4. Position the lower fixed bar under the object being ranged.
5. By pressing the UP (10)/DOWN (12) buttons, move the upper horizontal bar relative to the lower fixed bar until the object fits entirely between the two bars. The distance to the object is automatically recalculated as you move the upper line.
6. Exit the rangefinder mode with a long press of the MENU (11) button or wait 10 seconds to exit automatically.

Notes:

• There are three predefined values for the reference objects: Hare – 0.3 m height, Boar – 0.7 m height, Deer – 1.7 m height.
• Before it appears on the display, a measured distance value is rounded up to 5m for larger values and rounded down to 1m for smaller values.
• To select the unit of measurement (Meters or Yards), go to the General Settingsmenu item => Units of Measuresubmenu.

1. Screw the tripod mounting plate into the socket (4) as far as it will go.
2. Mount the Telos device with mounting plate on the tripod.

Is your firmware up to date?

Click here to check the latest firmware for your device.

It is recommended to inspect your device before each use. Check the following:

• The device should be free of any cracks or deformations.
• The lenses should be free of cracks, grease, dirt or debris.
• The battery level of the device should be full. Electrical sockets should be free of salts, oxidation, or other debris.
• All controls should be responsive.

Maintenance should be carried out at least twice a year and should include the following steps:

• Wipe the exterior surfaces of metal and plastic parts with a cotton cloth. Do not use chemically active substances, solvents, etc. as these will damage the paint.
• Clean the electrical contacts of the rechargeable battery on the device using a non-greasy organic solvent.
• Check lenses of objective, eyepiece and rangefinder. If necessary, remove dust and sand from the optics (it is preferable to use a non-contact method). Cleaning of the exterior surfaces of the optics should be done with cleaners designed especially for this purpose.
• Store the device in a carrying case. Remove the Battery Pack for long-term storage.
