CRM-220 Fast Track Guide

Connevans recommend using rechargeable nickel metal hydride

batteries. However, if you wish to try out your new CRM-220

immediately, you can alternatively use alkaline PP3 batteries.

Fitting batteries

To fit a battery, slide open the battery cover, insert as shown.

Although there is a battery polarity label in the CRM-220

between you and me you can actually fit the battery either way

around and it will still work!

Rechargeable nickel metal hydride (NiMH) batteries

New rechargeable batteries require charging before use, the

charger recommended by Connevans is an intelligent quad

charger (Part no. 22684).
1

Plug in the batteries to be charged. New batteries will need

a firm push into the charger – we would suggest using the

flat of the hand. Try lifting the battery a little, if it comes

straight out it was not pushed in properly. 

2

Instructions for using the quad charger 

are simply:
a) Insert battery 
b) don’t touch ‘mode’ button 
c) battery is charged when display 

shows ‘RDY’.

The performance of the CRM-220 is the same
whatever type of battery is used.
