Battery Storage
1. Fully charge a battery before you store it for a long time, to avoid battery damage due to
over-discharge.
2. Recharge a battery after several months’ storage (Ni-MH & Ni-Cd batteries: 3 months;
Li-Ion & Li-polymer batteries: 6 months), to avoid reducing battery capacity due to
over-discharge.
3. Store your battery in a cool, dry place under room temperature, to reduce self-discharge.
Charging Operation
When the radio flashes red LED and sounds low-pitched tone at intervals of ten seconds,
indicating the battery power is low, please charge the battery by the HYT approved charger. The
