• When possible charge battery packs only when they are completely discharged, i.e. when the
battery icon has no bars inside.
• Don’t remove the battery from the charger before the necessary time to provide a full charge.
• Provide at least two deep charge/discharge cycles per month.
• The best way to avoid memory effect is to use two battery packs and alternate their use with the
radio. This will allow you to keep on your transceiver’s operation by replacing the battery pack just
when it’s fully discharged and use the spare (charged) one. At the end of your working day you will
charge the discharged pack for 8 hours.
Erasing memory effect
Memory effect can be easily erased just by applying 3-4 deeper charge/discharge cycles:
1) Use the battery fitted in the radio and wait till the radio switches off.
2) Wait at least one hour and then try to switch on the radio: you will note that some energy has restored
in the battery, because the radio can be switched on.
3) Leave the radio in RX until the radio switches off again.
4) Repeat steps 2) and 3) three times.
5) Fully charge the battery for 9 hours and check the battery duty. If some memory effect still exist go
back to step 1.
!
If the battery duty doesn’t improve after three of the over stated cycles, it means that your battery
pack is faulty or has reached the end of life (please see “Information on rechargeable batteries”).
In this case please ask your dealer to provide a new battery pack.
