13. PRECAUTIONS WHEN HANDLING RADIO CON-
TROL
13.1 TRANSMITTER
The structure is not fully waterproof, so do not put it in water or wash it in water. In addition, store it in a place
where there is low humidity and little change in temperature.
The case is made of ABS resin, so it may become deformed if it is left in direct sunlight for a long time or wiped
with thinner or other solvent.
Put on the shoulder belt and chest protector provided with the equipment, and be careful not to drop it or sub-
ject it to any excessive impact.
Always keep the terminals and connectors of the battery clean and be careful not to let any rust form.
13.2 RECEIVER UNIT, CONTROLLER
The structure is not waterproof or bacteria proof, so close the storage box lid to prevent it from being immersed in
rainwater.
13.3 CHARGER FOR AC, DC
The charger structure is not waterproof or bacteria proof, so use it in a place where no water can get on it.
Do not subject it to vibration or impact.
Always keep the terminals and connectors of the battery clean and be careful not to let any rust form. Exces-
sive dirt may cause defective contact.
The charger is equipped with a circuit that detects any drop in the external voltage and stops the charging.
The charging cut voltage is 22.5 V and the restoration voltage is 23.5 V. If the charging is cut, the timer is
reset. If the power switch is turned OFF during charging, the timer is also reset. In such cases, be careful not
to overcharge when starting
the charging again.
The applicable temperature when charging the battery is 0°C to 45°C. Always keep the temperature within
this range when charging.
(At temperatures below 0°C, the consumption rate for the gas generated during charging is reduced, so the
internal pressure rises, and this causes deterioration of the battery performance. At temperatures above
45°C, the charging efficiency is reduced.)
Store the battery within a temperature range from -20°C to 50°C. High temperatures will cause self-discharge
of the battery.
Charging is more difficult after the battery has been stored for a long time and the capacity is reduced, but
after it is repeatedly charged 2 - 3 times, the condition will return to normal.
When the battery is stored, be careful not to short circuit the terminals with coins or other metal objects.
