To replace the ear pad, remove the worn/damaged ear pad from the ear cup and
replace it with a new pad.
The battery charger should be placed on a flat surface such as a desktop or table
in a clean, dry environment.
If the indicators fail to light during charger operation, clean the contacts using an
alcohol–moistened cotton swab.
Avoid dropping batteries.
Do not carry batteries in your pockets or leave them in hot, damp or dirty places.
Clean the battery contacts periodically using an alcohol–moistened swab.
Be careful not to short the battery contacts together.
Do not set the batteries contact–side down on a bare metal countertop-especially
if it is damp.
When the battery voltage becomes too low, a short, low–volume tone sounds in
the headset at seven–second intervals to alert the operator to replace with a fully
charged battery.
The “battery voltage low tone” continues for two minutes after which the
headset turns off automatically to prevent damage to the batteries.
To charge a battery, insert the battery in one of the charging slots as shown in
Figure 18.
