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 “ low battery tone” continues for two minutes after which the
headset turns off automatically to prevent damage to the batteries.
ü Note
When installing a battery, make sure it is fully charged. It is important to
remember that an unused C1060 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. Slide and hold the battery release. See Figure 11.
2. Remove the discharged battery from the battery housing.
3. Insert a fully charged battery in the housing with the notch facing the
battery release. Make sure the battery is fully inserted (battery release
clicks). See Figure 11.
