[. . . ] To avoid this, select an appropriate delay time that allows your entire transmission to be sent, before Transmit mode ends. 1 Enter Menu mode and access Menu 136. 2 Set the desired delay time to 250, 500 (default), 750, 1000, 1500, 2000, or 3000 ms. · When VOX is activated, the " " icon, gain level, and delay time will appear on the display. Note: If you press [PTT] while the VOX function is ON, the VOX Delay Time is not reflected to the transmission. If you press [CALL] (if 1750 Hz is programmed) to transmit a 1750 Hz tone, the VOX Delay Time is not reflected. If the DCS function is ON, the transceiver remains in Transmit mode for the duration set by the VOX Delay Time. It then sends a Turn-Off Code to close the receiving party's squelch. OTHER OP ­ 5 VOX on Busy You can configure the transceiver to force VOX transmission even if the transceiver is receiving a signal. 1 Enter Menu mode and access Menu 137. POWER ON PASSWORD If power on password is activated, you cannot operate the transceiver without first entering your password, after turning the transceiver power on. Your password can be changed using the MCP-4A software, and can contain up to 6 digits. 1 Enter Menu mode and access Menu 19A. 2 Set it to "On" or "Off". Note: You can press [PTT] or [CALL] (if 1750 Hz is programmed) to transmit, regardless of the setting in Menu No. 137. 2 Set the power on password to "On" or "Off". · When set to "On", "PASSWORD" appears on the display. MASKING BANDS If you have no plans to use a certain frequency band, you can hide the frequency display on the unused band. 2 Press [A/B] + Power ON. · The band mask display appears. 3 Enter your password. 4 After entering up to 6 digits, press [ OK] to set the password. 3 Press [ ]/[ ] or rotate the Tuning control to select the band you want to hide (or return to normal). 5 Press [ ]/[ ] or rotate the Tuning control to set the band to select "Use" or "Mask". · "Use" allows you to see and use the band as normal. "Mask" hides the band on the display. Note: Even with Menu 19A turned on, the power on password function will not be activated unless you first program a password using the MCP-4A software. 6 Press [ OK] control to set the selection. 7 Press the [ESC ] to exit. Note: You cannot operate the masked band nor use it to receive or transmit. You cannot mask all frequency bands. OTHER OP ­ 6 GPS (GLOBAL POSITIONING SYSTEM) What is GPS? GPS, standing for Global Positioning System, is becoming common nowadays. The American Defense Department developed GPS originally for military operations. For example, anybody can use GPS in association with modern vehicle navigation systems. Moreover, precision can be improved when a vehicle is used for navigation and aboard ships through use of map matching technology and differential GPS techniques. A total of 24 or more GPS satellites are at a high-level altitude of approximately 20, 000 km on six circular tracks with an orbital radius of approximately 26, 000 km. Therefore, there are four or more satellites located in each orbital track. For civilian use, the RF carrier frequency of the satellites is 1575. 42 MHz. [. . . ] When activated, this function will check for a received NOAA 1050 Hz tone. When the tone is received, the weather alert tone will sound. WEATHER ALERT ON/ OFF 1 Enter Menu mode and access Menu 13A. WEATHER ALERT SCAN The memory channel only for the weather alert is scanned. 1 Enter Menu mode and access Menu 13B. 2 Set the Weather Alert to "On" or "Off". · · When activated, the " " icon appears on the display. When a signal is being received, the " " icon blinks. 2 Set the Weather Alert Scan to "Off" or "15/ 30/ 60 (min)". [. . . ]
