PACKING LIST:Beside this manuał, the carton contains the following items:1. Transceiver2. Carrying case with shoulder strap3. Earphone case with earphone4. 2 pcs. dummy batteries inside the battery case

GENERAL DESCRIPTIONThe SOMMERKAMP 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 25KHz incréments. The operational channei number is displayed by large attractive LED numerics.

FEATURES AND CONTROLSVOLUME/ON-OFFThe 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-ONThe 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 SWITCHThis toggle switch w ill change the Channels electronically. By pushing it forward, the channei number w ill 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 SCANNINGOne 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 SOMMERKAMP 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.

UNPACKING AND CHECKOUTUnpack 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 fu lly counter-clockwise position. Press the dent of the battery compartment lid and pull it out toward the bottom of the set. L ift 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 i t 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

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.

OPERATIONSwitch 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 w itha normal voice into the microphone located befjind the front g rill. A fter completing your trans- missJon, release the PTT switch. The transceiver w ill then be ready for réception. Always remember that your opposite party cannot hear you while he is trans- m itting 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 fu lly counter clockwise. To switch the transceiver off, turn the volume control fu lly 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 w iii not damage the transceiver.The same applies, should the transceiver be used continuously with an external power supply.

POWER SOURCESThis 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 STANDOn the bottom of the cabinet, there are battery charger contacts provided. Consuit a SOMMERKAMP 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 le ft 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 9It is so designed that the transceiver is switched on always with the channel 9 which is the Emergency Channel.
