Battery use

Batteries may be charged hundreds of times but gradually wear out. When the operating time
(stand-by and talk time) is noticeably shorter than normal, it is time to buy a new battery.
If the battery is totally empty the battery level symbol may not be displayed at once when con-
necting the battery charger. Moreover the mobile cannot be turned on. Up to 15 minutes may be
necessary to reach the required 4% battery charge to turn your mobile on and allow the battery
charge symbol to be displayed. Battery charging may only operate between 0°C and + 45°C.
- Do not leave batteries connected to a charger longer than necessary. Overcharging shortens
battery life.
- Disconnect battery chargers from the power source when not in use.
- Do not expose batteries to high temperatures or humidity.
- Do not dispose of the batteries in fire. They may explode.
- Avoid putting the batteries into contact with metal objects which can short circuit the battery
terminals (e.g. keys, paper clips, coins, etc.).
- Do not drop or subject the batteries to strong physical shocks.
- Do not try to disassemble any of the battery packs.
- Use only specified Mitsubishi charger (see above).
- If the battery terminals become soiled, clean them with a soft cloth.
- Batteries may warm up during charging.
Caution:
Risk of explosion if the battery is replaced by any other battery than the Mitsubishi MA-0803..
Battery disposal
In compliance with European environmental protection directives, used batteries must be
returned to the place of sale, where they are collected free of charge.
Do not dispose of your batteries within household waste.
