  • Page 28

    Additional Operations NOTE Using this procedure in Memory mode to switch from one squelch mode to the other, does not affect the default squelch mode for the channel. Each time you turn the radio off and on again, or when you switch to another channel and back again, the radio reverts back to its default squelch mode.

  • Page 29

    Additional Operations NOTE If you reach the upper (‘15’) or lower (‘00’) limit of the squelch range, the squelch level does NOT wrap around to the opposite limit but remains where it is. Selecting The Receive PL / DPL Squelch Code NOTE Receive PL / DPL squelch code selection can only be done in MHz mode.

    Memory Mode Operations NOTE The radio remains in MHz mode after successful programming of the channel. CAUTION If the selected memory channel was already pro- grammed (channel number lit continuously), the new frequency information overwrites the previous information. Loading A Memory Channel The data of a memory channel (receive and transmit frequencies, TX offset type and offset frequency) can be copied over into the MHz mode.

  • Page 42: Scan Operations

    Scan Operations Scan Operations Scan operation tells the radio to monitor a number of frequencies or channels. When there are some activi- ties at a particular frequency or channel, the radio stops scanning and changes to that frequency or channel. Scan modes supported by the radio are: (i) Programmable Band scan (MHz mode) (ii) Memory Channel scan (Memory mode)

    Scan Operations SCAN Press to begin scanning the preprogrammed N-DEL frequency range. NOTE The frequency range is scanned according to the frequencies specified in channels 19 and 20, and the selected frequency step size. If the operating fre- quency before scanning starts is within the scan range, the radio starts scanning from that fre- quency, otherwise, it starts from the frequency specified by memory channel 19 (or the lowest fre-...

  • Page 44

    Scan Operations NOTE Pressing Push-To-Talk (PTT) Button (6) , a digit on the numeric keypad, also ends the scanning. NOTE The ‘SCAN’ indicator turns off when scanning is terminated and the radio displays the frequency where scanning stopped. IMPORTANT If both memory channels are left blank (unpro- grammed), the radio scans the entire frequency band.

  • Page 46

    Scan Operations NOTE The radio scans through all channels in the prepro- grammed scan list. If activity is detected, the radio stops scanning and stays on the active channel. The ‘SCAN’ indicator remains on, and you will hear the conversation, provided the PL/DPL code (if required) is correct.

  • Page 47

    Scan Operations NOTE Two medium-pitched “beeps” are sounded indicat- ing the radio has temporary removed the Nuisance Channel from its scan list. IMPORTANT To add a deleted nuisance channel back into the scan list, exit and reenter the scan function or restart the radio.

    Information For Safe, Efficient Operation Electromagnetic Interference/compatibility Nearly every electronic device is susceptible to elec- tromagnetic interference (EMI) inadequately shielded, designed or otherwise configured for electro- magnetic compatibility. • Turn your radio OFF in any facilities where posted notices instruct you to do so. Hospitals or health care facilities may be using equipment that could be sensitive to external RF energy.

  • Page 72

    If your radio fails to operate or any operational difficulties arise, contact your local Motorola dealer. Proper repair and maintenance procedures assure efficient operation and long life for this radio.

  • Page 76: Troubleshooting

    Troubleshooting Troubleshooting Radio is dead. Possible Problem (1): Batteries may be dead (alkaline) or not properly charged (NiCd). Solution :If the display does not light, or the ‘BATT’ indicator flashes on and off, you should replace the alkaline batteries, or if you are using NiCd batteries, recharge them.

  • Page 77

    Troubleshooting Possible Problem (3): The battery life is based on a duty cycle where the radio is transmitting 5%, receiving 5%, and in standby mode 90% of the time. Usage that differs from this will change the typical battery life expect- ancy accordingly.

  • Page 78

    Troubleshooting Radio will not talk to other radios in system. Possible Problem (1): Radios may be on different fre- quencies, having different Coded Squelch Codes. Solution :Verify that frequencies and Coded Squelch Codes are the same for all radios in your talk group. Hearing other conversations or noise on your radio.

  • Page 79

    Troubleshooting Possible Problem (2): Operating the radio while it is close to your body (i.e. in a pocket or on a belt) and while you are using audio acces- sories decreases its range because of the shielding effect of your body. Solution :The higher the radio is held, the better the talk range.

    Possible Problem (1): The radio may need to be repaired. Solution :If the unit is still under warranty, return it to the place of purchase for repairs, or contact your nearest Motorola dealer listed in your local yellow pages. 2-Year Warranty...
