In this case, the channel must be monitored manually as follows: Noise - The transmitter is disabled if a carrier is detected on the channel. Rx Indicator - With scanning disabled, note if the indicator on the top panel is steady green. If it is not, the channel is not being used and you can transmit your call.
OPERATION 1. Using the number keys, enter the number of the channel that is programmed with the code you want to reassign to all channels (only channels 1-9 can be selected). See Section 2.6.2 for information on displaying channel numbers. Tone Call Guard Squelch Tone-type Call Guard squelch utilizes subaudible CTCSS tones from 67-254.1 Hz. Although there are 42 tones assigned, those above 33 (210.7 Hz) are normally not used because of their close proximity to the voice band which starts at 300 Hz.
OPERATION If a Project 25 (digital) channel is selected, pressing this switch selects the emergency mode and if the PTT switch is pressed, an emergency status is sent. Radio power must be turned off to cancel the emergency mode on a Project 25 channel. you are out of range of the repeater, you cannot talk to anyone else on that channel even though the mobile you are calling may be only a short distance away.
OPERATION 0.25-4.00 seconds in 0.25-second steps can be programmed. No Priority - No priority channel sampling occurs when the list is selected. The radio transmits on the selected channel. Lookback Time B - This time determines how often the priority channel is checked once an incorrect Call Guard (CTCSS/DCS) or NAC code is detected.

Press the PTT switch and the call proceeds as follows: Individual ID - Each transceiver that operates on Project 25 (digital) channels is programmed with an 8-digit individual ID. This ID is unique for each transceiver and can be any number from 1-16777216. When power is turned on with a Project 25 channel selected, this ID is briefly displayed.
OPERATION (cycling power does not reselect the old talk group). Proceed as follows: analog channels: SecureNet™ and 460 scrambling. More information on these protocols follows. 1. Select the channel to be changed and then press the Talk Group Select option switch. SecureNet SecureNet is a proprietary Motorola protocol that digitizes the voice and then encrypts it using the DES algorithm. It provides the highest level of security. There are two DES protocols: 2.
OPERATION With the SecureNet protocol, the following receive options can be programmed: with the 460 Scrambler, a Clear/Secure option switch may be programmed. Pressing this switch changes the transmission mode for the selected channel and momentarily displays either “CLEAR” or “SECURE”. No Autodetect - Only signals coded like the transmit signals are received.
OPERATION at a fixed location). Most calls you make will probably be this type. Receiving a Standard Call When a SMARTNET/SmartZone group call is received, the transceiver can be programmed to display the Individual ID of the calling mobile and/or the received talk group alias. The Individual ID is briefly displayed when the call is received and the talk group and channel alias are then alternately displayed (if applicable). Placing a Standard Group Call 1.
OPERATION 3. Press the PTT switch to initiate the call. The display then indicates the alias of the destination radio. If the entered digits do not correspond to a valid list entry, “INVALID” is displayed and an error tone sounds. Proceed to the bulleted list following the next method for other conditions that may occur next. • If the called party answers but the radio system is busy, four low tones sound and “BUSY” is displayed. When the system is no longer busy, the call back tone sounds.
