|Vaisala recommends using the rechargeable battery pack (item code 26755) with GM70, instead of alkaline batteries.|
If you are using alkaline batteries, unscrew the back plate of the indicator and insert the batteries. Do not attempt to recharge standard alkaline batteries.
If you ordered MI70 with a rechargeable battery, it is already in place as shipped from the factory. The delivered batteries have been pre-charged.
To recharge the rechargeable battery:
- Plug in the charger connector to the MI70 indicator. The socket is located at the top of the indicator, covered by a rubber seal.
Connect the charger to a wall socket. An animated battery icon in the left corner of
the display indicates that the battery is charging. The recharge duration (typically 4 … 5
h) depends on the charge level of the battery.
A new battery takes approximately 3 charging cycles to reach its maximum capacity. Do not store the batteries empty. Empty batteries may not charge after an extended storage period.
