86 Manpack Transceiver 2110 series Repair Guide
Checking the battery charging process
You may use any of the following chargers to charge the battery:
• a 3121 AC Battery Charger (1 A), which uses a universal AC mains input of 90 to
264 V AC
• a 3122 DC Battery Charger (1 A), which may be powered from any 12 to 60 V DC
source (for example, from a 12 V DC outlet in a vehicle, or from a 24 V vehicle
battery)
• a 3123 Fast AC Battery Charger (3 A), which uses a universal AC mains input of
90 to 264 V AC
• a solar battery charger and lead (1 A nominal in full sunlight)
• a hand-powered battery charger (1 A at 60 rpm)
The Codan 3121 AC Battery Charger and 3122 DC Battery Charger are specially
designed for low-noise operation, so receiver performance remains optimal while
charging the battery pack via the front panel.
NOTE
The 3123 Fast AC Battery Charger connects directly to the battery pack
for charging. You cannot use this charger through the 19-way or 5-way
connector on the front panel of the transceiver.
CAUTION
Charging is recommended between 0 and 40°C (104°F). The battery will
not commence charging if the temperature is at or above 40°C (104°F). If
charging is already in progress, and the temperature rises to 50°C (122°F),
charging is stopped automatically.
CAUTION
To prevent damage to the battery, Codan recommends the use of the
Codan battery chargers to charge the battery pack.
