INTRODI ICTION
Your RadioShack FRS radio is a portable. easy-to-use, two—way mdio that you can carry
almost anywhere, Use it at Shnpping malls, amusement parks. sports- events, or at the bcach
to contact family and friende, or for vital communications in a neighborhood watch
Your radio has 14 channels. and 38 different quiet codes, If someone else is using the
channel you selected and you do not want to hear that person, select another channel or use
the quiet l'cature. You can talk with a person who has an FRS radio if both radios are tuned to
the same channel and quiet code
Your radio has auto-squelch, which mcans you will not hear anylhing on a channel unless
someone is transmitting nearby on the same channel You can turn inflame—squelch to hear
weaker, distant transmissmnt
Also, if the radio is idle for 2 hours‘ the automatic shut ol'l'timcr turns it off The radio turns
on again when you prcs> PUSH TO TALK
You can connect an optional speakerr‘microphone and earphone, charger (not supplied) to the
radio, And, the belt clip lets you take your radio almost anywhere

ALIGNMENT PROCEDURES
Important: The FCC requires that any frequency adjustment on a radiophone must be done
by authorized person, who is the holder of a current first or second class radiotelephone
license,
This unit has been fully aligned at the factory before shipment and does not normally require _
further adjustment. When necessary, however, the unit may be aligned as indicated below,
Do not adjust any circuit in this radiotelephone unless you understand the circuit operation
and have experience adjusting radiotelephoner Tampering with the rudiotelephone may
upset the alignment and lower its performance.
Test Equipment Required
The following equipmentis requred for the alignment.
Regulated DC power supply, 0~l2V,1A or higher; or 8,4V, 1A
Audio signal generator,IOHz~2Kl-Iz
Digital multimeter
Deviation meter
Frequency coutner,ON500MHz high impedance
Oscilloscope
RF power meter, SW

CIRCUITS AND DEVICES TO STABILIZE FREQUENCY
SYNTHESIZER
A phase locked loop (PLL) circuit establishes and stabilizes
operating frequency.
The data for producing necessary frequencies is established
by the CPU on the digital board.
The frequency stability of the Tx/Rx is maintained by the
TCXO, which generates a stable frequency of 12.8 MHz.
