the internal beltpack charger is used to attempt to charge them.
Damage and possible injury will result.
Rechargeable AA-size NiMH (nickel-metal hydride) batteries may be
used with the Eclipse beltpack. Select good quality batteries with high
amperage ratings for the best and longest performance. These
batteries will last for many charge cycles, and will power the beltpack
for approximately 8 hours.
If you are charging the batteries twice daily, then the battery lifetime
would be approximately 8 months. It is recommended that the
batteries be replaced every 4-5 months in these circumstances.
Note: Eclipse beltpack usage times are dependent upon the
batteries used. Some batteries require more
charge/recharge cycles than others to reach their rated
capacity.
Figure 1-7: Battery Discharge Characteristics
The beltpack front-panel display has an icon that shows the battery
condition. It has five vertical lines to signify the remaining charge.
When the icon has dropped down to the last two lines, or if it drops
quickly after being turned on after previous use, it will be time in the
next few minutes to recharge the batteries (if rechargeable ones are
being used) or replace them. The beltpack will turn off by itself at low
battery levels.
Within the menu structure of the beltpack, a low-battery alarm is
available and may be set. When activated and when the battery level is
sufficiently low (approximately 40 minutes of remaining battery life) the
headset user will hear a beep at intervals and the battery indicator will
flash to indicate that the batteries must be replaced or recharged soon.
This setting is available under Alarm Options.
The Eclipse beltpack features an internal battery charger circuit, with
intelligent circuitry to prevent overcharging. It is powered via the pin
connector on the bottom of the beltpack, using the supplied universal
power supply. A thermistor (temperature-sensing device) measures
the change in temperature of the battery when charging, letting the
circuit know when to cease charging the batteries.
Spare clips of four batteries are available by contacting the Sales
Department.
