Maintenance
Avoid heat, humidity
DO NOT place the unit in direct sunlight or on a hot surface for extended periods.
Store the unit at room temperature. Keep the unit well ventilated and away from flames or other heat sources.
Charge BEFORE you start using for the first time
After unpacking the unit for the first time, please charge the unit for about eight hours. This is absolutely necessary as
the built-in rechargeable battery might have been discharged, due to transportation or being stored for extended
periods, despite being fully charged at the factory prior to shipment.
Charge fully
Ensure that the battery is fully charged BEFORE you store the unit. To maximise battery life and maintain performance,
make sure you charge the battery every month.
• When you need to use the unit again after a long period of storage, make sure you charge it fully
for at least eight hours BEFORE any operation.
• Please also charge this unit at the end of a period of operation to ensure a longer battery life
This unit has a DOD (depth of discharge) protection circuit built in. When the POWER switch LED flashes red, this
indicates the battery has depleted to a point where normal operation is not possible, it will shut down automatically.
This is to prevent permanent damage to the battery due to deep discharge. If this occurs please shut down the unit
and place it on charge immediately.
This unit has an inbuilt circuit to protect against overcharging. This will switch off charging once the battery is fully
charged. Useful hint: You can still operate the device whilst charging.
Replacing battery
Make sure the substitute battery is in compliance with specifications. Using an incorrect battery may lead to explosion
or malfunction.
Remove the batteries from the transmitter when it will be sitting unused for an extended period to prevent
damage from leaking batteries.
Charging contacts
Clean the charging contacts regularly with isopropyl alcohol to ensure a good connection with the charger.
If you are unable to remove any corrosion when it occurs, then contact your place of purchase for repair.
