Battery Check - Ortovox F1 classic Mode D'emploi

BATTERY CHECK

When switching on the bayonet lock switch, the control lamp will flash approx.
30 times at an interval of 2 times per second. Thereafter the flashing speed will slow
down showing the perfect functioning of the device. When the batteries go flat, the
number of quick flashes will decrease. If the device shows less than 5 quick flashes,
please change the batteries. If you perceive only 5 flashes, a sufficient safety of
1-2 hours work in receiving mode, at a temperature of -10°C is still guaranteed. The
battery capacity highly depends on the temperature. Therefore we recommend carry-
ing along spare batteries if there are only 15 flashes or less in order to be prepared
in case of need.
The battery check can only be repeated after a 3 minutes pause!
The visual control light only flashes if the device is in "transmitting mode".
ATTENTION!
Battery contacts can oxidize and therefore have to be cleaned if the
device has been out of action for a long period, especially after the summer. We
recommend taking the batteries out of the device during the summer and replacing the
batteries with new ones when the winter season starts. Do not use rechargeable bat-
teries (i.e. NiCd accumulators). They will become defective if the discharge is too strong
and will, after recharging, only regain their full power for a very short time. Moreover,
due to their lower voltage, the range and working life of the device are much shorter!
DANGER OF LIFE!
there are great differences of capacity especially at low outside temperatures.
For that reason we explicitely recommend only high quality alkali-manganese batteries
as they are like those that are provided with the initial beacon purchase (Do not use
photo-batteries).
Due to extensive testing of various batteries we found out that
