When the JB69 battery voltage is low the LOW BATT annunciator will flash once every 1.5 s and output a low battery
notification (a triple beep) in the headphones once every minute until the battery charge reaches critical voltage
level.(A similar but lower pitched tone will be heard if the paired JB60 Headset Adapter battery charge is low.)
Note
:
JAC recommends that the batteries should be charged or replaced immediately when the LOW BATT
warning illuminates during use.
When the unit battery charge is less than or equal to the critical battery voltage, the unit will turn off.
