Battery/Charging
When a cue tone is heard in operation, or the indicator
flashes red, it means that the battery is low. You need to
recharge it fully.
IMPORTANT:
1. Always use the Audex-specified AC charger.
2.
How to ensure the best use of the battery:
In order to prolong the lifetime of the battery(3xAAA
standard Ni-MH rechargeable batteries). we suggest
you recharge the device fully when the battery is low. Each
battery has a lifetime of about 500 charging cycles.
When the device is left unused for a long time after being
charged, the battery will be discharged. You have to
recharge the device for at least 10 hours until the battery
is fully charged. When the charging begins, the red light
will go on; the red light will go off after the battery is fully
charged.
Always remove the AC/DC charger from the power
source when you're going to leave your office, home or
car. Never leave them connected to the socket or
cigarette charger for a long time.
