How to recharge the unit
To recharge the unit, turn it OFF (0) and connect the adaptor to the unit. Connect the adaptor to the electrical power supply; making sure that the electrical power
supply voltage is the same as the adaptor's (the unit's LED will light up to show that the batteries are being charged). When you charge the batteries for the fi rst
time, the unit must charge for at least 24 hours; after that the charging time drops to 8 hours.
An 8-hour charge will provide about 45 minutes use. After charging is complete, disconnect the adaptor from the power supply and then remove the connecting
plug from the base of the unit. The unit is now ready for use.
REMARK: the electrical power supply may become slightly hot. This does not indicate any abnormal operation of the unit.
Precautions to take when charging the batteries :
1. To ensure maximum battery life :
- DO NOT charge the unit continuously for periods longer than 3 days.
- Do NOT operate the unit from the mains power supply if the batteries are fully charged.
- Do NOT charge and do NOT store this unit near to radiators or other sources of heat or in places where it is exposed to direct sunlight.
- Do NOT recharge this unit in a damp place, check that the temperature of the room does not drop below 0°C (32°F) and does not exceed 40°C (104°F).
- We suggest that the unit be completely discharged every two to three months and then completely recharged. Allow the unit to operate until it stops
functioning, switch it off and then recharge it fully.
2. Disconnect the unit from the electrical power supply when it has fi nished charging.
