1. 4 Pin Microphone Connector
2. On/OFF Volume Knob- Turn clockwise to turn power on
and set to the desired listening volume.
3. Squelch Knob- This control is used to cut off or
eliminate receiver background noise in the absence of an
incoming signal. For maximum receiver sensitivity it is desired
that the control be adjusted only to the point where the
receiver background noise is eliminated. Adjust until the
receiver noise disappears. This will require the incoming signal
to be slightly stronger than the average receiver noise. Fur-
ther clockwise rotation will increase the threshold level which
a signal must overcome in order to be heard. Only strong
signals will be heard at a maximum clockwise setting.
4. XTRA Talk Mic Gain Knob- Adjusts the microphone gain
in transmit and PA modes. This controls the gain to the extent
that full talk power is available several inches away from the
microphone. In the Public Address (PA) mode, the control
functions as the volume control.
5. RF Gain Knob-Adjust as required to optimize signal. This
control is used primarily to optimize reception in strong
signal areas. Gain is reduced by counter clockwise rotation
of the control.
6. Delta Tune Knob- Turn this fine tuning knob clockwise to
capture a more readable signal, as well as eliminate adjacent
channel interference.
7. SWR Knob (Standing Wave Ratio)-Allows for the
calibration of the meter for standing wave ratio measure-
ments.
8. Guardian Alert Knob- This unique feature allows for the
setting of a timed alert that can be used for many different
things including keeping one alert while driving or setting an
appointment reminder. To activate, turn the knob clockwise
to choose a time increment- 1, 5, 10, 15, 20, 30, 40, 50, or 60
minutes. Once set, the radio will emit a loud beeping noise in
the specified increment. For example, if you set the alarm for
15 minutes, after 15 minutes the alarm will sound. To snooze
the alert for another 15 minutes, press the knob in once.
To deactivate, turn the knob to the OFF position. Warning:
The Guardian Alert is NOT intended as a substitute for
adequate rest. You should not operate a vehicle if you
are drowsy. During extended periods of vehicle operation,
you should take frequent breaks. NEVER OPERATE A
VEHICLE IF YOU ARE DROWSY.
Feature Operation
Midland Radio Corporation is not responsible for
personal injury, vehicle damage or death due to negligent
use of the 9001z.
9. Channel Selector Knob- This knob selects any one of the
40 Citizen Band channels. The selected channel is indicated by
the LED readout, directly above the Channel Selector Knob.
10. C-MIC/DYM Switch- Allows the user to switch the type
of microphone being used. It can be set to use an Electret
microphone (C-MIC) or a Dynamic Microphone (DYM).
11. S/RF/SWR/CAL Switch- This switch selects meter
function. S/RF is normal, SWR and CAL are for SWR
measurements only. See pg 6 for calibration instructions.
12. NB/ANL/OFF Switch- When this switch is in the NB
position, the RF Noise Blanker will be activated. The RF
Noise Blanker is very effective for cutting down on ignition
interference. When in the ANL position, the ANL is active to
reduce background noise.
13. CB/WX/PA Switch- This switch allows you to move from
CB mode to Weather (WX) scan mode and PA mode. When
the Weather scan is activated, the radio will begin scanning
and lock on the first weather channel broadcast signal
strong enough to use. If later the signal becomes too weak
to use the unit will automatically resume scanning to find a
usable signal. In PA mode, incoming CB transmissions will be
broadcast through the PA speaker. This allows you to hear
transmissions when you are not inside your vehicle. The PA
function should not be used unless a PA speaker is connected.
14. CH9/Nor/CH19 Switch- This switch is used for instant
selection of Emergency Channel 9, Informational Channel 19
or Normal CB operation.
15. BRT/DIM Switch- Used to adjust the brightness of the
LED.
16. XR Switch- This activates and deactivates the XR
technology, which is a noise filter than helps improve tran-
smission range.
17. TX LED- Indicates when the radio is transmitting.
18. ANT LED- Indicates a high SWR condition with the
antenna system. Check antenna, cable and connections.
19. WX LED- Indicates when weather mode is activated.
