For Best Performance
Battery Charge
The handset is powered by a rechargeable Nickel­Metal Hydride (Ni-MH) battery. Charge the battery for 6hours before initial use (p. 9).
Base Unit Location/Noise
Calls are transmitted between the base unit and handset using wireless radio waves. For maximum distance and noise-free operation, the recommended base unit location is:
Away from electrical appliances such as a TV, personal computer or another cordless phone.
In a HIGH and CENTRAL location with no obstructions such as walls.
Raise the antenna.
Note:
• If you use the handset near a microwave oven which is being used, noise may be heard from the receiver or the speaker. Move away from the microwave oven and closer to the base unit.
• If you use the handset near another cordless phone’s base unit, noise may be heard. Move away from the other cordless phone’s base unit and closer to your base unit.

Recharge
Recharge the battery when: —“Recharge battery” is displayed on the handset, —“7” flashes, or —the handset beeps intermittently while it is in use.
• The display will continually indicate that “Recharge battery” and/or “7” will flash when the handset battery is charged for less than 15 minutes and the handset is lifted off the base unit.
• If the battery has been discharged, the handset will display “Charge for 6h” and “8” when you place the handset on the base unit. The handset will not work unless the battery is charged. Continue charging.
Battery replacement:
If you cleaned the charge contacts and fully charged the battery, but after a few telephone calls, “Recharge battery” is displayed and/or “7” continues to flash, or “Charge for 6h” and “8” are displayed, the battery may need to be replaced. Please replace with a new Panasonic HHR-P104 battery. To replace the battery, see page 9.
A nickel metal hydride battery that is recyclable powers the product you have purchased. Please call 1-800-8-BATTERY for information on how to recycle this battery.
Battery information
Recharge battery
After your Panasonic battery is fully charged, you can expect the following performance:
• A fully charged battery will give you up to 5 hours of continuous talk time, or keep your handset in Standby mode to receive incoming calls for up to 11 days (if no phone calls are made). Battery power is consumed whenever the handset is off of the base unit, even when the handset is not in use. The longer you leave the handset off of the base unit, the time you can actually talk on the handset will be shortened. Actual battery performance depends on a combination of how often the handset is in TALK mode and how often it is in Standby mode.
Clean the charge contacts of the handset and the base unit with a soft, dry
cloth once a month. Clean more often if the unit is subject to grease, dust or high humidity, otherwise, the battery may not charge properly.
• If the battery is fully charged, you do not have to place the handset on the base unit until “Recharge battery” is displayed and/or “7” flashes. This will maximize the battery life.
• If you want to keep the battery fully charged at all times, place the handset on the base unit when the handset is not used. The battery cannot be overcharged.
While in use (TALK) Up to 5 hours
While not in use (Standby) Up to 11 days
