Midland 75-785

40 CH AM HANDHELD CB TRANSCEIVER

78-785 is a 40 channel Citizen Band Mobile operation, that is big on

performance. e radio is usable both in professional and private situations,

is a quality piece of electronic equipment, skillfully constructed from the nest

components. e circuitry is all solid-state, mounted on rugged printed circuit

boards. It is designed for many years of reliable, trouble-free performance. Your

radio has a Phase Locked Loop synthesizer circuit that incorporates technique

for generating all required frequencies with few crystals, resulting in much

tighter frequency control and superior reliability.

MAIN FEATURES

• Condenser microphone.

• Ceramic lter: Delivers greater selectivity and reduces adjacent channel

interference.

• AGC (Automatic Gain Control) for a constant sound level.

• Automatic modulation control for a constant audio transmit modulation level.

• Low distortion IC audio circuit.

• Automatic noise limiter to reduce pulse noise.

• “HI-LO” switch: Reduces the output power.

• Antenna with BNC connector.

• Jack for external power source and battery charger.

WARNINGS

• While 75-785 has been designed for many years of reliable, trouble-free

performance, it is a precision piece of electronic equipment that should not be

exposed to water or to extreme temperatures.

• Do not leave batteries installed over a long period of time as leakage may

occur and cause damage to the radio.

• Never use dierent batteries from the ones suggested.

• Clean the unit with a damp cloth only, never use harsh chemicals.

FCC

CARE OF OPTIONAL RECHARGEABLE BATTERIES

e following is meant as general information regarding Ni-Cd batteries.

• Always allow the battery to fully charge before using.

• Allow the batteries to fully discharge before recharging. Full discharge will be

indicated by the

“BATT. LOW” indicator.

• e above will prevent the batteries from developing “memory” which

eectively reduces their capacity.

• It is better to store Ni-Cd batteries that are discharged rather than charged.

• Never use batteries which dier from the ones recommended. Do not mix

old and new batteries or batteries of dierent capacities.

• If you experience problems when using the transceiver, check the following:

1. Batteries must be in good condition.

2. e volume level and squelch control setting.

3. e channel selector for an active channel.

4. e antenna must be properly inserted.

CONTROLS AND INDICATORS

1. Antenna connector with BNC connector: To obtain better results, use either a

telescopic or an external antenna.

2. Squelch Knob: for the maximum receiver sensitivity, the control must be

regulated exactly where the receiver background noise disappears.

3. On/O Volume Control: Turn the control clockwise to switch on the unit.

Continue turning the knob clockwise to set the audio level, until you get a

comfortable reception.

4. Display: Indicates the selected channel (from 1 to 40). e display turns o

when the squelch is operative.

5. “BATT. LOW” LED: is indicator lights when the batteries are low. Replace

the alkaline or recharge the AA Ni-Cd batteries.

6. “TX” LED: e indicator lights when the unit is transmitting

7. Speaker

8. Microphone: during transmission, hold the microphone two inches from your

mouth, speaking in a clear, normal voice.

9. Push to Talk Button (“PTT”): By pressing it, the transmitter is activated.

When released, you activate the receiver.

10. “Channel UP” button: Tunes to the next channel. Autorepeat is activated by

holding this button.

11. “Channel DOWN” button: Tunes to the previous channel. Autorepeat is

activated by holding this button.

12. “SPK” jack: external loudspeaker jack (the internal loudspeaker will be

disabled).

13. “PTT/MIC” jack: PTT jack / external microphone.

14. 13.8 VDC Charge: Power supply/charge jack. You can power the unit from

external sources (car battery, etc.) and to recharge the Ni-Cd batteries.

15. “HI/LOW” Switch: Selects the output power level during transmission.

16. Battery Compartment: Insert 9 AA alkaline or Ni-Cd batteries. (Note:

alkaline batteries are not rechargeable).

17. NI/AL Switch - Ni-Cd / Alkaline battery type switch

18. Belt Clip

19. Hole for wrist strap
