Maintenance
Model C860
14
3M 2003 January
When the battery voltage is too low, the headset sounds a short, low-volume
tone at seven-second intervals to alert the operator to install a fully charged
battery. The “battery voltage low tone” continues for two minutes after which
the belt pack turns off automatically to prevent damage to the batteries.
Note
When installing a battery, make sure it is fully charged. It is important to
remember that an
unused
C860 battery loses five percent of its charge per
week. If a battery has not been used for several weeks, make sure to charge
prior to use.
To replace the battery:
1. Push the battery release to release the battery. See Figure 14.
2. Remove the discharged battery from the belt pack.
3. Insert
a
fully charged battery
in the unit. Make sure the battery is fully
inserted (battery release clicks). See Figure 14.
Note
The C860 can operate on one battery or two. Using two batteries doubles the
operating time between charges.
If two batteries are used, both must be recharged at the same time.

To replace the headset pad, remove the worn/damaged ear pad from the ear cup
and replace it with a new pad.
