Troubleshooting ~ "won't charge".

Tip 1

Ensure that the cords (power and telephone line) are plugged into the channels on the bottom of the base/charger. If the cords are not properly installed, the base may not sit level. This can cause the phone not to make contact with the base and the handset will not charge.

Ensure that your cordless handset is cradled properly.  When placing the handset in the charging base, confirm that the charge contacts on the handset and base are making a good connection. The CHARGE light on the telephone handset will be on when the handset is charging.

Tip 2

For mulit handset systems:


To determine if the handset or charger is defective, place the handset in another charger or base.  If the charge light comes on, replace the defective charger.  If the base is defective, replace the whole unit.



For single handset systems or when all HS's are affected follow the steps below:


If the handset is not responding normally, you may need to reset your telephone system. Complete the following steps to reset the telephone system:
Step 1: Disconnect the power to the telephone base.
Step 2: Disconnect the handset battery(s).
Step 3:Wait a few minutes and then reconnect the power to the telephone base.
Step 4: Reconnect the handset battery(s).
Step 5: Wait about one minute for the handset to re-establish a link with the telephone base and then test the phone again.


NOTE: After resetting the telephone system, you will need to reset the clock:


Step 1 When the phone is not in use, press MENU/SELECT.
Step 2 Press DIR or CID  until you see >SET DATE/TIME.
Step 3 Press MENU/SELECT.  Use the dialing keys to set the month date and year.
Step 4 Press MENU/SELECT.  Use the dialing keys to set the hour and minute; then press DIR or CID  to select AM or PM.
Step 5 Press MENU/SELECT  to confirm your settings.  Press and hold OFF/CANCEL to return to the idle screen.

Tip 3

Dirty charge contacts on the telephone base and handset could prevent the batteries from charging. Clean the handset and base charge contacts using a pencil eraser or a cloth to eliminate deposit accumulation.


Tip 4

Confirm proper installation of the telephone base power supply and handset battery. You should only use the power supply provided with your telephone. Make sure the power supply is not connected to an electrical outlet that is controlled by a wall switch. Confirm that the electrical outlet that the telephone is plugged into is working.


Tip 5

Ensure that the battery cover is installed correctly. When correctly installed, the batttery cover should be flush with the handset. If there are any spaces or gaps around the battery cover, the unit may not charge properly.


Tip 6

If the battery is less than 1 year old and talk time is less than 3 hours, replace the battery.  If the battery is more than 1 year old and there is an issue with the battery, customer may need to purchase a new battery.
