Battery life guidelines
Primary battery (non-rechargeable)
The primary non-rechargeable battery pack is capable of providing
sufficient power for the specified 8 hours according to regulations.
The battery is marked with an expiry date. Replace the battery at or
before this date.
To ensure a long lifetime keep the battery in the store position in the
charger and avoid high temperature and direct sunlight.
Secondary battery (rechargeable)
During daily use, always keep the battery fully charged and away from
hot areas.
Keep the battery terminals dry and clean.
Never discharge beyond the specifications of the battery.
Operation/Standby time depends on usage. Generally, the more the radio
is transmitting, the faster it will drain the battery. Also, the “Hi” power
setting will drain the battery faster than the “Lo” setting.
Approximate figures are:
• A battery can be stored for 4 to 6 month at 25°C if charged to 25%.
• The battery will normally last for 5 to 9 hours of use on a fully
charged battery.
Note New batteries should be placed in the charger for minimum 12
hours first time.
