2.2. Power Supply
2.2.1. Base Station
 Plug the AC power adapter into the Base Station’s DC jack and connect to
the mains power. Make sure that you use an adapter with the appropriate
AC voltage rating to prevent component damage. An AC-DC 12V/2A
switching power adapter is generally used to power the standard version
of the Base Station.
 In addition to the AC power adapter, a rechargeable battery is installed
inside the Base Station to serve as a backup in case of a power failure.
 During normal operation, the AC power adapter is used to supply power to
the Base Station and at the same time recharge the battery. It takes
approximately 72 hours to fully charge the battery.
 If the battery switch is set as OFF, the battery will not be charged when
AC power is connected and nor will it serve as a backup power source
when AC power is missing. You need to switch the battery to ON for it to
be charged when AC power is connected and serve as a backup power
source when AC power is missing.
 When the Base Station is experiencing an AC power failure or low on
battery, it will not charge the Mobile Unit.
2.2.2. Mobile Unit
 Charge the Mobile Unit battery by inserting the Mobile Unit in the charging
base on the Base Station. In addition, a travel charger (to be purchased
separately from the Mobile Pers package) can be used to charge your
Mobile Unit when you are away from home.
 When the Mobile Unit is being charged, LED 1A (green) blinks every 2
seconds. When the Mobile Unit is fully charged, LED 1A (green) is steady
on.
 The Mobile Unit needs to charge for 4 consecutive hours for its low battery
status to return to normal battery status. Please use the Mobile Unit after
LED 1A (green) and the Base Station’s yellow LED are both steady on to
indicate the Mobile Unit has fully charged.
 When the Mobile Unit is low on battery, LED 1B (orange) blinks every 3
seconds.
 The Mobile Unit makes a low battery report to the CMS when it is running
low on battery.
 The Mobile Unit makes a battery restored report to the CMS when its
battery is fully recharged.
 When the Mobile Unit is low on battery, it plays the voice prompt: “Mobile
Unit battery is low. Please charge it.”
