Page 39: Ale Submenu
(25) FREQ INC HZ determines how much a frequency increments or decrements each time an arrow button is pressed. This is used when the frequency value is being changed. Available increments are between 1 Hz and 10 MHz. The default setting is 100 Hz. (26) TEST REAR PANEL I/O tests the back-panel accessory con- nectors. -
Page 40: Ale Submenu
To access the ALE submenu, press ALPHA, 17, and E. There are two ways to move through the ALE submenu: Press the desired function number and press E.

Once a function is entered, the arrows are used to scroll through any further settings within that function. - Page 41 Table 3-2 ALE Submenu Function Description ERR THRSD (error threshold) MESSG OUT (message out) NEW MESSG (new message) MESSG IN (message in) HANDSHAKE NET ADRS (network address) NET NAME (network name) NET SLOT (network slot) NET OTHER (network other) EXIT MENU (1) SCAN RATE controls the rate at which scanning proceeds.
- Page 42 (12) SND LEN sets the length of each sounding transmission. The recommended sounding length is 5 or 10 seconds. (13) SND INT sets the TW7000 to sound in time intervals from 1 minute to 24 hours (0001 to 1439 minutes).
- Page 43 (20) BER THRSD controls the bit error rate threshold (00-48) for received ALE words. A threshold of 00 would allow for no errors, while a threshold of 48 would be the maximum amount of allowable errors. The default setting is 48 errors. (21) GOLAY THD controls the error correcting capability threshold (0-4).

Page 44: Customizing Channel And Frequency
Customizing Channel and Frequency The TW7000 associates a frequency, mode, clarifier status, and offset value (if on) to each channel number. These can be different for each channel and are recalled whenever that channel number is entered. Once frequencies are set to channels, channels can be placed in scan groups. - Page 45 Example: To change the frequency of channel 041 from 13.330,000 MHz to 8.572,000 MHz: Press C, 041, and E. Display: CH FREQ 041 13.330,000 MHz Press F, 8.572, and E. Display: CH FREQ 041 8.572,000 MHz Assigning Semi-duplex Frequencies To select the channel and assign a new frequency: Press C, enter the 3-digit channel number, and press E.

Page 46: Scanning
Data is retained in the manual channel. Scanning Scan groups are arranged in the TW7000 according to number. There are 32 scan groups available in the radio at one time, each one having a different scan group number. Each scan group can contain up to 64 channels. - Page 47 Selecting a Scan Group A scan group must be selected before customizing can be per- formed. Use the following procedure to select the scan group: Do one of the following: If ALE is ON, press SCAN GROUP or select (2) SCAN GRP from the ALE submenu.

IS call. As soon as the link is established as being poor, press CALL to terminate the link. Press CALL again and select RE-LINK. Press CALL a third time and the TW7000 attempts the link again using the second best channel. This can be repeated for subsequent channels until the link quality is acceptable. - Page 50 001-255 and not assigned to another transceiver. Display: xxx (briefly displays the new receive code) Selcall: To start a call with Selcall, the TW7000 must be set to a fixed channel (not scanning) and a call initiated. Press OPTION until the TCSC icon flashes.
- Page 51 Note: When scanning in Transcall, the receiving station also responds to a valid Selcall. TransAdapt: The TW7000 can be on a fixed channel or in scan mode. If on a fixed channel, TransAdapt operates the same as Selcall. If in scan mode, TransAdapt locates the first usable frequency, not the best.
