Replacing Fuse; Antenna System - Midland ALAN 54 E Bedienungsanleitung

The most common mounting position for a transceiver is under the dashboard directly over the drive shaft hump. Do not
mount the transceiver in the path of the heater or air conditioning air stream. Take your time and plan your installation
carefully. When you have determined the best location or mounting, use the mounting holes. Take care when you drill the
holes that you do not drill into wiring, trim or other accessories. Mount in position with bolts, lock washers and nuts or self-
threading screws. You can install this transceiver in any location where 12-13,8 V DC power is available. It can be connected
to negative ground system. Just be sure you connect the RED wire to the (+) terminal and the Black wire to the (-)
terminal.
Connect the RED wire (with in-line fuse holder) to the accessory terminal on the ignition switch of your vehicle. Make a
good mechanical and electrical connection to the frame of the vehicle for the black wire. You can use an auto accessory
lighter plug, available on the CB-market, to connect your transceiver to the vehicle's cigarette lighter receptale. However,
is better to connect the DC power cord directly to the accessory terminal of the ignition switch. This will prevent unauthorized
use of the transceiver, and will also prevent you from leaving it on unintentionally. Before operation, you must install and
connect your antenna system. The lead room the antenna you've installed should be connected to the antenna coaxial
connector. I you are using an external speaker, connect it the EXT-SPKR jack.

REPLACING FUSE

If you replace the fuse for DC Power cord, use 2 Ampere type (one supplied as spare). Hold the fuse holder and press on
the inside, then rotate the holder.

ANTENNA SYSTEM

A mobile antenna system is not limited to just the antenna. The transmission line as
well as the vehicle are important factors in the total antenna system. Therefore, you must use the correct type of transmission
line and mount the antenna securely in a position that will give you optimal results.
Use coaxial cable with an impedance of 50 Ohms. We suggest type RG 58/U for lengths under 2,5 m or RG 8/U or longer
lengths. Generally speaking, you should keep the length of the transmission line to a minimum.

The above discussion is as important for reception as it is for the transmission. If a mismatch exists between the antenna
and the receiver, the excellent sensivity and signal-to-noise radio of the receiver circuit will be defeated.
MOBILE ANTENNA
A few general rules should help you install any mobile antenna properly.
Keep it as far as possible from the main bulk of the vehicle.
Keep as much of it as possible above the highest point of the vehicle or boat.
During operation, it must bee vertical, and rigid enough to remain vertical when the vehicle or boat is in motion.
Mount it as far as possible from sources of noise (ignition system, gauges, etc.) and keep the transmission line away from
these nose sources.
An antenna mounted in a boat requires a good ground connection. This can be either a metal hull or a ground made off tin-
foil or copper sheeting. This ground should cover an area of a least 1 m2 or more. Be sure the transceiver also has an
adeguate ground.
There are many types o mobile CB antennas: a full quarter-wave length hip, a center- loaded whip, top loaded type, you
will find it a physically shorter antenna. But, for greater efficiency the 2,5 m long, full quarter wave whip is better. Antenna
length is directly related to efficiency. Generally, the longer is the more efficient.
There are many possible antenna locations on a car.
