Motorola MT2000 manual Tx Power Select, Trunk Repeater Offset, Channel Assign Type, Rx Modulation

CHANGE/VIEW MTSX RSS

FIELD DEFINITIONS:

System

Use the up/down arrow keys to scroll from system number 1 to the number of systems in the radio.

Tx Power Select

The transmit power may be reduced 1 watt for 800 and 900 MHz models, and 2 watts for VHF and UHF models. Factory default is High. This feature is not available for all models.

DEPENDENCIES:

The power levels selected will depend on the alignment values, which can be adjusted under the alignment section in the Service portion of this RSS package.

Trunk Repeater Offset

The value must be set to the frequency separation between the transmitter and receiver frequencies used at the central repeater site. Factory default is 45MHz for 800 band and 39 MHz for 900 band.

Channel Assign Type

Sets the channel assignment type to Domestic or International. Domestic - 25 KHz channel spacing used in the USA. International - 12.5 KHz channel spacing used outside the USA.

Splinter Channel (800 MHz Only)

The control channels will be shifted down 12.5 KHz and the radio will interpret the channel numbers received over the air as splinter channels as well. Channels in the 821 band will not be affected. Factory default is Disabled.

Rx Modulation

This field should be based off of the expected receive data format for the personality. This field allows the user to configure the radio's personality for strictly binary (2-level) receive operation, strictly multi-level (4-level) receive operation, or both binary and multi-level receive operation (Auto Receive). When operating in Auto Receive mode, the radio will automatically detect the received signal type and process the data accordingly. As a side note, however, 2-level sensitivity is reduced when operating in the Auto Receive mode and thus should not be used on channels or systems that are strictly binary (2-level). This field applies only to Secure radios.

Channel Bandwidth

Use the UP/DOWN arrow keys to select the Channel BandWidth. This value must be set to the Channel BandWidth of the system the radio is to operate on.

NOTE

Strapping fields for Announcement Group, Fleet ID, Talkgroup, etc.will be forced to 'Clear' if 12.5 kHz is selected.

The factory default is 25.0 kHz.

ISW Retry Timer

Use the up/down arrow keys to select the value for this field.

This field changes the interim spacing between ISW retries. Spacing between retries is extended to accommodate System access delays. Valid entries are Disabled, 25ms, 50ms, and 75ms. Factory default us Disabled.

Phone DTMF Timing

Timing may be changed for Initial Delay, Digit Duration, and Inter Digit Delay. The radio contains a table with four sets of values of these parameters. The actual parameters are entered on the Radio Wide Phone Configuration screen (F4/F3/F4/F9). Factory default is 1.

NOTE

For non-keypad models-This option can ONLY be used with the One Touch

Button Feature (Main Menu F4/F4/F3/F9/F5).
