Important information on charging
and using rechargeable batteries
4.
First use: Charge new batteries in one continuous, uninterrupted,
charge until they are full. This first charge may take longer than
normal. For longer battery life it is advised to always recharge in
one continuous, uninterrupted charge until batteries are full, do not
recharge again while the batteries are still full.
5.
New batteries will only reach their full capacity after some time of
use (several charge and discharge cycles).
6.
Leave the complete group of batteries in place inside the radio and do
not use these batteries or a few of them for other purposes. This will
result in a mix of (fully) charged and (partly) empty batteries. This can
seriously damage the batteries and radio when recharged.
7.
It is advised to only charge batteries at room temperature between
5 degrees C – 35 degrees C. In lower or higher temperatures full
charge may not be achieved.
8.
Depending on the capacity of the batteries, charging from "empty"
to "full" can take several hours, even up to 7 hours or more.
9.
Do not charge batteries when the radio is hot or exposed to heat or
heat sources.
10.
It is advised to clean the metal contacts of the batteries and of the
charger inside the radio e.g. with a contact-spray from time to time.
11.
Do not use a mix of old and new rechargeable batteries.
