! THE LEGEND CONTINUES, RUGGED AND EASY HANDLING!

Back to the myth, updated and improved!!

Alan BS 48 is a full team for the truly demanding amateur.


- Mic Gain controls the gain of the microphone to achieve always perfect modulation
- RF GAIN: Control to vary at will the preamplifier gain antenna
- IDF: Control to regulate the tone of the received signal
- ANL: automatic noise limiter
- PA: Pressing this switch, the device becomes a low frequency amplifier (with additional speaker)
- Front-lit

1. LEGAL NOTES

The transceivers use of CB27, is subject to obtaining the

corresponding administrative leave by the Administration

Spanish. To obtain all necessary information about it, contact

the Provincial Telecommunications province. Also

can get all the information you need by calling 913 461 500 or

However, in the website of the Ministry of Science and Technology

www.sgc.mfom.es / directory / directorio.htm, which offers a

convenient access to the data of all the Provincial Headquarters. Also

www.alan.es both our website as your attention to

cliente 902 38 48 78, will keep you closely informed of

legal developments and requirements for this and other procedures

related to the CB.

2. DUTIES AND POSITION OF CONTROLS

1. S-METER / SWITCH / CHANNEL CONTROL SIGNALS

At the reception indicates the level of the signal received at the scale

19 30 dB

In transmission, shows the RF power leaving the

transmitter (Watts)

Channel selector with LED display of the number.

Moving the control clockwise or counterclockwise

appears on the display a number that represents the channel

operating (see table below the corresponding frequency)

With the selector (CB% u2013 PA) PA position display does not

lights.

Flare (AW1): Only active if the transmission line

There are anomalies (broken antenna, bad connections, broken wire)

Flare TX: Fires when the device transmits

2. MICROPHONE

CONNECTION

Insert the connector into the socket 4 pin team

respecting the guide notch. Then, thread

the clamp until it is firmly attached

TRANSMISSION

To transmit, hold the

PTT (located on the side of

micro) throughout the period

transmission. Correct, acting with the

MIC-GAIN for perfect

modulation. Respect, as far as possible, that the cord is

Extended.

3. CONTROL ON / OFF Volume (power and volume)

In the OFF position the transceiver is off. Turn this control to

the right to turn the unit. Continue turning slowly

clockwise to achieve the desired audio level. With the

PA-CB switch in position PA, will handle the audio output level

by the external speaker (optional).

4. SQUELCH CONTROL (silencer)

For maximum receiver sensitivity, this control

adjusted exactly at the point where noise disappears

background.

5. RF-GAIN CONTROL (RF gain control)

Controls the sensitivity of the reception. To increase

sensitivity, turn right. The sensitivity decreases

turning it counterclockwise. The low sensitivity is useful when

signals on the channel are very strong.

6. MIC-GAIN CONTROL (microphone gain control)

TX mode, controls the amplification of the microphone. For

best results, use the original microphone and put it to Alan

optimal distance from your mouth (5-10 cm.) and the level of amplification

correct, asking his colleagues at what point

modulation is optimal.

7. SELECTOR ANL / OFF

ANL position activates an automatic noise limiter

caused by impulses (caused by motor car or other

sources)

ALAN BS 48 User's Manual 3

8. FIL-OUT SELECTOR

IDF position (beep) activates a tone control to get better

broadcast signals. OUT position (standing) the control is

disabled.

9. SWITCH CB / PA

In the CB position, the unit operates as a transceiver. You can use the

function PA (public address) only if its available

a speaker (optional) connected to the PA. In this case, the button

"Volume" controls the amplification.

3. INSTALLATION

The safety and ease are the primary considerations for

the mounting of any mobile equipment. All controls must

be easily accessible to the operator, without interfering in the correct

driving. Choose the perfect location in the vehicle

where to set the transceiver and use the supplied stand or, possibly, a

sliding support (optional). Put the screws. Support

attachment must be in contact with metal parts.

Note: we remind you that is absolutely forbidden to use microphones

handheld mobile communications (in vehicles). There are in

market "hands-free kits" that allow you to use the radio without the need

to remove his hands from the steering wheel, keeping the performance of equipment and

greatly increasing both their safety and that of other

drivers.

4. CONNECTION

Make sure the transceiver is off. In feeding

DC is very important to observe the polarity, even if

unit is protected against an accidental inversion:

Red = positive ( )

Black = negative (-)

The same colors are present in the battery and the box

Car fuse. Correctly connect the cable to the terminal

battery.

5. ANTENNA INSTALLATION

1. Install the antenna as high as possible. Follow the instructions given

the manufacturer.

2. Typically, the longer the antenna, enhanced performance

obtained.

3. If possible, mount the antenna on a large surface (roof) and

this center.

4. Keep the antenna cable shielded from noise sources such as

the ignition of the car, etc.

5. Make sure you have a solid grounding, metal

metal.

6. In the event that can not meet as described in the previous section,

we inform you that there are special antennas on the market not

require a ground plane. Also on hand is a type of cable

antenna connection that simulates an artificial ground plane. In both

cases, installation can be achieved that performance

entirely satisfactory.

7. Avoid damaging the antenna cable during installation thereof.

Warning: To avoid causing serious damage to equipment, never operate

its radius without being connected to a suitable antenna.

We recommend periodic testing of the cable and the ROE

installation.

6. OPERATING TRANSCEIVER

1. Connect the microphone jack.

2. Make sure the antenna is connected to the computer.

3. Make sure the squelch control is turned fully

the left.

4. Turn the unit on and adjust the volume control.

5. Select the desired channel.

6. In the absence of signal, adjust the squelch (squelch) to eliminate

background noise.

7. To transmit, hold the PTT button and speak to about 10 cm.

the microphone and with a normal tone.

8. To receive, release the PTT.
