1. To enable it on LTR Net and LTR telephone and auxiliary calls check the Conversation Enabled box in the Basic Parameters screen Proceed Tone Delay The proceed tone normally sounds almost immediately when the PTT switch is pressed However if the user should wait a short time after pressing the PTT switch before speaking for example when wide area calls are placed a delay of 0 2 5 seconds can be programmed in the Timing Parameters screen This delay can then be enabled on each group by checking the Delayed Proceed Tone box If this box is not checked no delay occurs 2 7 3 LTR NET MODE SCANNING LTR and conventional systems are now scanned in the LTR Net mode in certain conditions Previously only the LTR Net systems in the scan list that accessed the current locality were scanned When both roaming and system scan are enabled registration on other sites occurs and the only systems scanned are LTR Net systems that are in the scan list and programmed for the current site However if no LTR Net locality could be located during locality search LTR and conventional systems that are in the scan list are also scanned If a signal is detected on one of those systems the transceiver moves to it However searching continues for a programmed LTR Net locality and when one is detected registration on that site occurs and only LTR Net systems are again scanned This operation can provide uninterrupted opera tion when t2. Therefore there should not be an X in the Option Switch column The Encryption Horn Alert and Mic Hook Sel Hanger functions are now available so Note 1 should be ignored 3 7 TRANSFER MENU The Read Codes and Read Factory Info parameters have been added to the Transfer menu shown above Read Codes was previously in the File menu These parameters function as follows Read Codes This menu item or toolbar icon reads the error code log stored in the radio and displays it Refer to Section 2 14 in the service manual addendum for more information Read Factory Info This parameter displays the pre ceding screen which indicates the following version 10 information for the transceiver connected to the computer ESN Indicates the electronic serial number of the transceiver that is stored in the logic Warranty Info This is the transceiver identifica tion number described in Section 1 3 see addi tional information on Section 1 3 on page 1 Radio Config These are digits 4 11 of the trans ceiver part number described in Section 1 4 see additional information on Section 1 4 on page 1 Software Version Indicates the version of operating software contained in the radio 3 8 VIEW MENU When the View gt Personality menu item is selected the left pane is displayed in the main screen see illustration on the top of page 8 Either the Locality Bank or System view type can

G TRANSCEIVER POWER For the transceiver to de register and save the current states of the various functions when power is turned off power to the transceiver must be main tained for a time after power is turned off Therefore observe the following when installing the transceiver and turning power off Connect the transceiver power cable to an unswitched power source such as the battery Do not connect it to a switched source such as the ignition switch or a relay Make sure that power is always turned off using the front panel power switch or the ignition sense input of the accessory cable Program the power off delay as follows If the ignition sense input is used program the Ignition Sense Delay parameter on the Main Radio Parameters gt Timing Parameters screen for the desired delay Immediate is allowed If the ignition sense input is not used program this Ignition Sense Delay parameter for Forever This prevents improper operation when the vehicle is started TRANSCEIVER TUNING The 98xx LTR Net transceivers can now be field tuned using a special procedure which re Flashes the transceiver with temporary operating software The following programs are required to tune this radio 1 LTR Net Personality Program P N 023 9998 457 This program is called LTRNetMobPgmr and it programs the information which changes from radio to radio This program is described in Section 3 of the 98
