Use of DC cables (optional)
Our DC cables and adaptors are only designed for operating the radio in a car or truck. They
cannot be used to recharge the batteries inserted in the battery compartments.
The DC cable connects to the DC socket on the side of the battery pack (inner contact + and
outer contact -)
It is technically not possible to charge the radio with inserted NiMH batteries from 12 V DC. With
engine off, no charge current is possible. With running engine, at 13.2 V, only a weak charging
current is applied to the NiMH battery, which can only keep the charging status, but cannot
recharge an empty battery completely. The technical circuit allows to connect the DC cable
permanently to the radio, and Alkaline batteries are switched off as long as the DC cable plug is
inserted.
230 V Wall Charger: Only this device can charge NiMH batteries in the battery compartment
completely. It supplies a higher (but current limited) voltage of 15..16 V and is matched to the
circuit. During charge procedure the radio must remain switched off.
Please make sure that You do not have Alkaline batteries inserted. Such batteries cannot be
charged and there is even a risk of explosion or excessive heat if You should try to charge such
batteries.
Note to the DC fuse
A DC fuse for 2 A current is inserted inside the cigarette lighter plug of the DC cable. If this fuse
should blow, please exchange only by a fuse of the same current range and try to find out the
cause! Our repair experience shows that in most such cases the polarity of the cigarette lighter
installation was wrong. Never repair a blown fuse by aluminium foil or similar material!
Warnings
Never try to charge Alkaline batteries Such batteries may explode, heat up, leak and can cause
injuries. If You are using rechargeable batteries, check from time to time that the battery and
battery holder contacts are clean and not corroded. Many NiMH batteries show corrosion or
leakage after longer time periods. Take out the batteries from time to time, clean the contacts
and check that they work. Cadmium containing batteries, like the former used NiCD batteries,
are not any more allowed to sell because of their environment risks.
Antenne connection
The supplied short plug in antenna allows only communications over short distances. Higher
communication ranges in CB can only be obtained by longer antennas up to a quarterwave
length (this is a physical law and on CB, a quarter wave is 2.75 m!). Any longer Antenna, mobile
or base station antenna can extend the range of Your radio considerably
It is allowed to connect other antennas to Your hand held radio. All You need is an antenna with
BNC (for example Nr. 6577) connector or an adapter between the normally used PL plug and
BNC.
