4. 2 pcs. dummy batteries inside the battery case

GENERAL DESCRIPTION
The SOMMER AMP TS-1122FM transceiver is designed for continuous heavy duty
portable use. It can be operated with an external antenna, a short rubber type
antenna, an external power supply, a headset, a a téléphoné-set incorporating
automatic voice operated transmit/receive switching and an external sélective
tone cali system PARROT 76 with automatic answer back and many more.
The transceiver is a 500mW output, frequency synthesized solid state radio
set, designed for FM transmission and réception in the 27MHz range.
Frequency control employs state of the art digital circuitry combined with a
précision phase locked VCO to provide 22 transmit and receive channeis in
25 Hz incréments. The operational channei number is displayed by large
attractive LED numerics.
FEATURES AND CONTROLS
VOLUME/ON-OFF
The transceiver is switched on as a click is heard rotating this knob clockwise.
The receiver volume is increased as it is turned further clockwise.
SQUELCH/LED-ON
The squelch control is used’ to eliminate background noise when there is no
signal present. То adjust the squelch, select a channei where there is no singal.
Turn the volume control knob to a normal listening level. Then rotate the
squelch control knob clockwise slowly until the background noise just disappears.
Rotating the knob marked LED/SQU to the right beyond an audible click will
switch off the LED channei display which would stay illuminated in a fully
counter-clockwise position.
CHANNEL UP/DOWN SWITCH
This toggle switch will change the Channels electronically. By pushing it forward,
the channei number will increase. Conversely, by pulling it, the channei number
decreases. Upon pushing or pulling this switch, the LED channei display will
light up but extinguishes automatically to save battery consumption if the
squelch control knob is turned to the right beyond the click.
AUTOMATIC UP/DOWN SCANNING
One of the unique features of this transceiver is the automatic up / down
scanning. Upward or downward automatic scanning is possible by pushing or
pulling the UP/DOWN toggle switch for a continuous few seconds.
On the other hand, the automatic scanning is also possible if the special
SOMMER AMP remote control microphone be connected to the 8-pin accessory
jack and the UP or DOWN button on the microphone be kept pushed for a few
seconds.
UNPAC ING AND CHEC OUT
Unpack this carton carefully and check for exterior damage. Verify if the
volume control is in the OFF position. The squelch control should be in its
fully counter-clockwise position. Press the dent of the battery compartment
lid and pull it out toward the bottom of the set. Lift out the battery holder
and insert 8 dry cells into the holder as indicated by the drawing.
+ plus to +, — minus to — pole. Leave the two dummy batteries in the holder.
Should you use rechargeable batteries, insert 10 pièces of them in the same
manner as above but remove the two dummy batteries. Snap the battery holder
into the snap connector provided and reinsert the holder into the compartment
Replace the compartment lid by inserting it straight from the bottom up until
it snaps into position rightly.
Extend the rod antenna to the full length. Now switch the transceiver ON by
rotating the volume control knob clockwise and check that the meter needle
moves into the green field. If the meter needle does not move at all.open the
3 —

battery compartment to remove the battery holder and verify that ail batteries
are inserted correctly.
Next turn the volume control clockwise unti! some noise is being heard from
the loudspeaker. Operate the ch'annel up/down switch to ensure that some noise
and/or signal is received.
OPERATION
Switch the transceiver on by rotating the volume control knob clockwise. The
set is immediately ready for transmit/reçeive on the CH-9. Select the desired
channel by operating the channel up/down switch. Adjust the volume control to
a comfortable level.
Press the PTT switch and talk from a distance of 5-10cm witha normal voice
into the microphone located befjind the front grill. After completing your trans-
missJon, release the PTT switch. The transceiver will then be ready for réception.
Always remember that your opposite party cannot hear you while he is trans-
mitting himself. Adjust the squelch control so that any background noise just
disappears. Perform squelch adjustment only during non-transmitting periods of
your opposite party.
To answer a received call, push the PTT switch and talk into the microphone.
To receive weak signais, turn the squelch control fully counter clockwise. To
switch the transceiver off, turn the volume control fully counter clockwise untii
a click is heard and the meter needie moves back into the red field.
Important Hint:
If the transceiver is not operated for a long time, remove the batteries from
the holder. This way, a decayed battery wiii not damage the transceiver.
The same applies, should the transceiver be used continuously with an external
power supply.
POWER SOURCES
This transceiver is designed to operate on a power supply of normal 12V DC
such as from internal dry cells or nickel-cadmium rechargeable batteries or
from an external power suppiy delivering at least 1 ampere. The set will,
however, operate from 10-16V DC without any damage. To use the set with an
external power supply, insert a plug of the power supply into the external power
jack provided.

BATTERY CHARGER STAND
On the bottom of the cabinet, there are battery charger contacts provided.
Consuit a SOMMER AMP dealer for the proper charger stand.
When you use rechargeable batteries, charge them either by plugging an ap-
propriate battery charger into the charger jack located on the left hand side
of the set or by inserting the transceiver into a battery charger stand.
Charge the batteries for about 14 hours. It is not possible to operate the set
during battery charging.
To connect the set to a 12V automobile battery, use a IA fuse in sériés with
the positive wire. Solder the positive wire to the center of the external power
pług and the negative wire to its fin.
For private listening, plug an earphone piece into the earphone jack provided.
The internal speaker will then disconnect automatically.
To operate the transceiver on a 50 ohm external antenna, connect it to EXT.
ANT jack provided on the top.
CHANNEL 9
It is so designed that the transceiver is switched on always with the channel
9 which is the Emergency Channel.
