HTX-212 Two-Meter Mobile Transceiver (190-1126) Using Memory Channels FaxBack Doc. #19153 The HTX-242 has 40 standard memory channels and one calling-frequency memory, where you can store frequently-used frequencies, along with all settings, for quick access. Storing a Frequency 1. Press VFO and tune to a frequency you want to store. Set all duplex and subaudible tone settings (see "Using Subaudible Tones" on Page 36), the transmit power setting, and the DTMF option. 2. To store the frequency in the calling-frequency memory, press and hold F for at least 1 second. FUNC flashes on the display. Then press CALL. To store the frequency in a standard memory, press F. Rotate TUNE, or press UP or DOWN on the microphone, until the HTX-242 displays the desired memory number to the left of the frequency. Then press MR. The HTX-242 beeps twice and stores all settings into the selected memory channel. Changing Stored Settings To change the receive frequency, follow the steps under "Storing a Frequency." To change the transmit frequency or a tone squelch option without changing the receive frequency, follow these steps. 1. To change the calling memory, press CALL. To change a standard memory, press MR. Then rotate TUNE, or press UP or DOWN on the microphone, to select the memory channel you want to change. 2. If you want to turn tone squelch on or off, repeatedly press T-SQL to select the desired tone squelch mode. (See "Using Subaudible Tones" on Page 36.) 3. For the calling-frequency memory, press and hold F for one second. Then press CALL. For a standard memory, press F, then press MR. The HTX-242 displays rF and the receive frequency, and M-CH flashes. 4. Rotate TUNE, press UP or DOWN on the microphone, or enter the receive frequency using the microphone's keypad. 5. Press UP ARROW. The HTX-242 displays tF and the transmit frequency. 6. Rotate TUNE, press UP or DOWN on the microphone, or enter the transmit frequency using the microphone's keypad. 7. Press UP ARROW. The HTX-242 displays rC and the current receive subaudible tone. 8. Rotate TUNE, or press UP or DOWN on the microphone, to change the receive subaudible tone. 9. Press UP ARROW. The HTX-242 displays tC and the current transmit subaudible tone. 10. Rotate TUNE, or press UP or DOWN on the microphone, to change the transmit subaudible tone. 11. For the calling-frequency memory, press CALL to save all settings. For a standard memory, press UP ARROW. The HTX-242 displays Sn. Rotate TUNE, or press UP or DOWN on the microphone, to select whether the memory is included in a memory scan (on) or locked out of a memory scan (Off). Then press MR to save all settings. Using Auto Memory Store (AMS) Follow these steps to have the HTX-242 scan through a selected range and store active frequencies in memory. 1. Set the upper and lower scan limits (see "Setting the Scanning Range" on Page 21). 2. Set the scanning step (see "Setting the Frequency Step" on Page 19). 3. Set the squelch (see "Setting Volume and Squelch" on Page 17). 4. Hold F for at least 1 second. Then press MHz. The HTX-242 scans between the lower and upper scan limits. When it detects a transmission, it checks all memories to see if that frequency is already stored. If the frequency is not in a memory, the HTX-242 stores the frequency in the lowest unused memory, then resumes scanning. The HTX-242 continues auto store until all memories are used. 5. To stop auto store before all memories are used, press VFO, DUP, MR, CALL, or MHz. NOTES: The HTX-242 turns off tone squelch during auto store. Auto store does not work if all memories are used. Tuning to a Standard Memory Channel 1. Press MR. 2. Rotate M-CH, or press UP or DOWN on the microphone, to select the desired memory channel. Using the Calling-Frequency Memory Press CALL. The HTX-242 recalls all settings saved in the calling- frequency memory. NOTES: If you rotate TUNE, press UP or DOWN, or directly enter a frequency, the HTX-242 returns to the last-used VFO. To return to the mode selected before you used the calling- frequency memory, press CALL again. Checking Priority Channel 1 To have the HTX-242 periodically "look back" at Memory Channel 1 to check for transmission, press F then ALM. SYMBOL appears on the display. The HTX-242 looks back at Memory Channel 1 every 4, 8, 12, or 16 seconds. If there is a transmission, the HTX-242 beeps to let you know to tune to it if desired. Follow these steps to change the look-back time. 1. Press VFO. 2. Hold F for at least 1 second. FUNC flashes. Then press MR. 3. Repeatedly press UP ARROW until the HTX-242 displays Lb and the current look-back time. 4. Rotate TUNE, or press UP or DOWN on the microphone, to select the desired look-back time (4, 8, 12, or 16 seconds). 5. Press MR or PTT to save the setting. Scanning Memory Channels To set the HTX-242 to scan memory channels, press and release MR. Then press and hold MR for at least 1 second. M-CH flashes, and the HTX-242 scans memories that have the scan option turned on (see "Enabling/Disabling Scanning for Memory Channels" on this page). The HTX-242 stops when it encounters a transmission. It resumes scanning according to the saved scan settings. To resume scanning immediately, press MHz. NOTE: Scanning stops if you press MR or PTT. Clearing a Memory Channel You can clear any memory channel except Memory Channel 1 and the calling- frequency memory. 1. Tune to the memory channel you want to clear. 2. Hold F for at least 1 second. FUNC flashes. 3. Press MR. All settings are cleared from the memory channel. Enabling/Disabling Scanning for Memory Channels You can disable (lock out) individual memory channels, so the HTX-242 does not stop on them when you scan memory channels. 1. Tune to the memory channel you want to enable or disable for scanning. 2. Press F, then press MR. 3. Repeatedly press UP ARROW until the HTX-242 displays Sn and the scan setting. 4. To enable scanning for the current channel, rotate TUNE, or press UP or DOWN on the microphone, to select on. To disable scanning for the current channel, rotate TUNE, or press UP or DOWN on the microphone, to select oFF. 5. Press MR or PTT to save the setting. (SP 02/16/96)
