2.1.2 When finished, power off backlight to prevent battery discharge during transportation and storage.
2.1.3. Do not open battery compartment of the product, replace batteries, remove protective lid of the battery
compartment and lens in the conditions of high humidity (over 90%), condensate, or the possibility of water
penetration into the interior content of the product and its parts.
2.1.4 Do not immerse the product into water, do not enable backlight in case of water ingress, do not operate the
product at temperatures beyond the limits specified in p. 1.2.16.
2.1.5. Replacement of battery should be carried out only when the device is powered off.
2.1.6 To prevent battery explosion, use the charger from the delivery set only for NI-MH batteries. Never charge
alkaline or other primary power elements in the supplied charger.
2.1.7. Avoid simultaneous charging of batteries with different degrees of discharge, as well as of different
capacities and different manufacturers.
2.1.8 Do not use charging device outside or inside the car.
2.1.9 Ambient temperature during charging should be in the range from plus 5ºС to plus 40ºС.
2.1.10 Do not insert leaked batteries or those with any signs of corrosion into the device or charger.
2.1.11 Rechargeable batteries can heat up during charging; after full charging, they gradually cool to room
temperature.
2.1.12 Do not store batteries in the device if the break in its use is more than 3 days.

- hit distal end with hard objects;
- use the endoscope to eliminate any objects preventing clear observation;
- throw the endoscope on hard surfaces, beat and shake it;
- bend the working side of the fiber bundle with a radius of less than 25 diameters of the working part;
- twist, straighten and bend the distal end of the endoscope with hands;
- make sharp turns of the distal end control knob.
2.2. Getting Started
2.2.1. Before using the device, make sure there is no violation of operational restrictions
2.2.2. Remove the device off the standard package.
2.2.3. Make sure there is no mechanical or chemical damage on the power units. Check for any mechanical damage
on the product.
2.2.4. Install operational and charged rechargeable batteries into the battery compartment of the device carefully
observing polarity.
2.2.5. Close battery compartment lid tight by pulling it to the case with a screw to prevent penetration of foreign
objects and water into the case while operating the device.
2.2.6 Press backlight power button to heck battery charge level. If battery indicator is green, battery charge level is
adequate. If the indicator flashes or stays in red and the backlight is off, then batteries need charging.
2.2.7 Batteries are charged on the charger of GP PB50GS270 type. The external view of the charger is shown in
figure 5.

2.2.8 To charge the batteries, follow these steps:
connect power cord to the charger and AC 220V / 50Hz. When properly connected, the green LED will be on
the charger's body;
install the rechargeable batteries into the charger strictly in accordance with the polarity indicated on the case.
During charging, opposite to the installed battery, there will be a battery charge channel indicator and the
lightning icon indicating charging process. After charging has been completed, the green indicator (tick) will be
on. While this the indicators of the corresponding battery charge channels will be on continuously. If a defective
battery or another type of battery is installed into the charger, the 'exclamation sign' indicator and the 'batteries'
indicators will be flashing frequently. In case of a malfunction of the charger, green power indicator and the
'exclamation sign' indicator will be flashing, and the charging process will not be launched;
after the end of charging, disconnect the charger from the 220V / 50 Hz network and remove the batteries using
the button located on the side of the charger body.
2.2.9. The approximate time of simultaneous charging of 4 batteries is shown in Table 2.
