* PSB (Public Service Band) ‘
On the PSB, you can monitor police, fire, forestry conservation, VHF weather,
marine, highway maintenance, land mobile, and other public safety radio
services. The general frequency allocation is shown on the dial scale.
NOTICE: !n certain localities, it is illegal to listen to police or other govern-
mental transmissions. Check with your loca! authorities.

FEATURES
@ The AIR-7 portable receiver receives the air traffic control fre-
quencies, 108-136 MHz, as well as standard FM and AM broad-
casts. With type 1 and 2 models, PSB, 144-174MHz, can also be
received.
@ The quartz controlled PLL (Phase Locked Loop) synthesizer
system uses a microcomputer to make pinpoint tuning easy.
The tuned frequency is displayed digitally.
@ Choice of direct, scan, manual or memory tuning.
@ Up to 40 (type 1 and 2 models) or 30 (type 3 and 4 models) sta-
tions can be memorized so that they can be tuned in at the press of
a key.
@ Air band and PSB can be received more easily with the memory
scanning, program function, priority function and delay function.
@ Squelch control to suppress noise while tuning and during
intervals between communications.
@ The key protect function operates at the press of a key to lock
the keys on the front face so they cannot be operated by accident.
@ Helical antenna for high sensitivity and selectivity has BNC con-
nector for attachment to the receiver.
e@ Four different power sources: batteries, house current,
rechargeable battery pack or car battery.
PRECAUTIONS
@ Operate the receiver only on 6V dc with four IEC designation R6
batteries (size AA).
For ac operation, use the ac power adaptor recommended for this
set.
For car battery operation, use the car battery cord recommended
for this set.
@ Use the set within a temperature range of 0°C to 40°C (32°F to
104°F). If it is used in temperatures outside this range, numbers
may appear’ on the display which have nothing to do with the fre-
quency being received. If it is used in temperatures lower than this
range, the numbers displayed may changed very slowly. These
irregularities will disappear and there will be no damage to the set
when the set is used in its recommended temperature range.
@ Do not leave the set near heat sources, such as radiators or air-
ducts, or in a place subject to direct sunlight, excessive dust,
moisture, rain, mechanical vibration, or shock.
@ Should any solid object or liquid fall into the set, remove the bat-
teries, and have the set checked by qualified personnel before
operating it any further.
@ When the case becomes soiled, clean it with a soft cloth
dampened with a mild detergent solution. Never use abrasive
cleansers or chemical solvents, as they may mar the case.
@ In vehicles or in buildings, radio reception may be difficult or
noisy. Try listening near a window.
@ When there is lightning and you are using an external antenna,
immediately disconnect the ac power adaptor (if connected) from
the wall outlet. Never touch the antenna wire when there is light-
ning storm.
@ Reception of 109.875 MHz, 166.17 MHz, 167.08 MHz and 455 kHz
may be difficult due to internal spurious signals generated by the
built-in oscillators.
lf you have any question or problem concerning your set that is not
covered in this manual, please consult your nearest Sony dealer.

power adaptor and the polarity of the plug must be as illustrated.
~
HOW TO CHANGE THE MW TUNING INTERVAL
The MW tuning interval is factory preset to 10 kHz (Canada) or 9 kHz
(other countries) to match the local frequency allocation system.
If you use the receiver in an area where the frequency allocation
system is based on the other interval, change the position of the
9kHz/10 kHz selector in the battery compartment as follows.
rear
ys
Co 9kHz/10kHz selector
Q9kHz 10kHz
1. Remove the batteries.
2 Switch the selector.
3 Wait at least 10 minutes, then put back the batteries in the com-
partment and close the lid.
Notes
@ If you replace the batteries within approx. 10 minutes after the
batteries are removed, the tuning interval will not be changed
although the selector has been switched. Be sure to wait for at
least 10 minutes.
@ After changing the MW tuning interval, memorize the stations
and functions again, as the previous memory may have been eras-
ed.
INSTALLATION OF THE HELICAL ANTENNA
For air band, PSB or FM reception, use the supplied helical
antenna.
Insert the projection of the set’s ANT connector into the siot of the
connector on the antenna, and turn the antenna clockwise until a
click is heard. See illustration (G] on page 4.

6 After listening, press the POWER switch again to turn the
receiver off (m OFF).
For AM reception, the built-in ferrite bar antenna functions. Since
this antenna is directional, rotate the set horizontally for optimum
reception, if necessary.
See illustration [H] on page 4.
12

Note: After pressing the DIRECT key or a counter key, press the
next key within 5 seconds. If you do not, the previous station will
return.
The frequency received by this receiver is displayed in steps of the
following intervals, depending on the bands.
AIR: 0.025 MHz
PSB: 0.005 MHz
FM: 0.050 MHz
MW: Q9kHz or 10kHz*
LW: 1kHz
SW: 1kHz
This is because the frequencies are allocated at these intervals.
Therefore, if you input a frequency between the interval, the fre-
quency at the interval just below will be tuned in and displayed.
For example, if you input AM 1,000 kHz with the tuning interval set
to 9kHz, AM 999kHz will be tuned in and displayed.
* This tuning interval can be set to 10 kHz or 9kHz by switching the
9kHz/10 kHz selector in the battery compartment. See page 11.
If you input a wrong frequency
Press the DIRECT key again and input the correct frequency.
The ! indication
If you input a frequency outside the frequency range (AIR
108-136 MHz, PSB 144-174 MHz, FM 87.6- 108.0 MHz for type 2
and 4 models, FM 76.0- 108.0 MHz for type 1 and 3 models, AM
150-2,194kHz), the indication [TRY AGAIN]! will blink in the
display. When you input a proper frequency, [TRY AGAIN)! in-
dication will disappear. If you leave [TRY AGAIN]! indication
blinking, it will disappear after about 5 seconds, and the tuned
station’s frequency will reappear.
Notes on antenna
@ if reception is unsatisfactory with the helical antenna or the
built-in ferrite bar antenna, connect an external antenna. To con-
nect an external antenna, see page 22.
@ In vehicles or in buildings, reception may be difficult or noisy.
Try listening near a window.

If scanning stops a little before a station, tune in the frequency
more precisely by manual tuning (See page 16.).
Note on scanning
Scanning is performed in the range of the band being received, at
the intervals shown on page 13. When the upper limit of the fre-
quency of that band is reached, the dial is scanned back to the
lower limit, and vice versa.
