Low Battery Alarm
LCD screen:
Warning
When a low battery alarm is generated, cease operation immediately and retrieve the
model.
If the battery goes dead while in operation, you will lose control.
Power supply and low battery alarm
The T4GRS can use an optional rechargeable battery. However, the battery alarm setting
is different from that of the dry cell battery (alkaline battery recommended). Therefore,
always set the battery type to match the power source used. Always set the battery type
to "N5/L2" especially when using a Futaba rechargeable type battery. If the set is used
at "DRY4" setting, the time from low battery alarm to system stopping will become ex-
tremely short.
