PRO-57 Scanner (200-0126) Operation Faxback Doc. # 19706 PROGRAMMING THE PRO-57 1. Select a Channel by pressing [PROGRAM]. Repeatedly press [PROGRAM] until the channel you wish to program is displayed. The "-" to the left of the channel number indicates the PRO-57 is ready to have a frequency programmed. 2. Enter a Frequency. Enter a frequency that is active in your area. An excellent reference for active frequencies is Radio Shack's "Police Call Directory Including Fire and Emergency Services". The directory is updated every year, so be sure to get a current one. Also, refer to "A General Guide to Scanning" Faxback Doc. # 19705. 3. Press [ENTER]. This stores the frequency you entered in Step 2. If you made a mistake in Step 2, the display shows "E" to the left of the channel number. Be sure the frequency you entered is in one of the bands your Pro-57 receives, then press [CLEAR] and proceed again from Step 2. 4. Press [DELAY]. If you want the Pro-57 to pause slightly after each transmission before scanning to the next channel, press [DELAY] so that the dot after the channel number turns on. If you do not want the Pro -57 to pause, press [DELAY] again to turn off the dot. 5. Press [PROGRAM] to program the next channel. Repeat Steps 2-4 to store additional frequencies (up to 10). USING THE RESET SWITCH The scanner's display might lock up the first time you connect power to it, or if power fails for more than one hour. If this occurs, use a pointed object, such as a paper clip, to press the reset switch on the back panel while the power is on. This procedure clears any information you have programmed into the scanner. Use this procedure only when you are sure the unit is not working properly. SETTING THE VOLUME AND SQUELCH Rotate the VOLUME control clockwise and the SQUELCH control counterclockwise until you hear a hissing sound. Then, slowly rotate the SQUELCH control clockwise until the noise stops. Leave the VOLUME control set to a comfortable level. If the scanner picks up unwanted partial or very weak transmissions, rotate the SQUELCH control clockwise to decrease the scanner's sensitivity to these signals. SCANNING THE CHANNELS Once you have stored frequencies into the channels, the Pro-57 can scan through these channels, searching for a transmission. Just press [SCAN]. The Pro-57 quickly scans all of the channels until it tunes a channel that has activity. When the activity stops, the Pro-57 resumes scanning. NOTE: If the SQUELCH control is set too low, so that the hissing sound between transmissions is continuously heard, the Pro-57 does not scan. LOCKING OUT A CHANNEL If there is a channel you do not wish to monitor, such as a continuously transmitted weather channel, press [MANUAL], the channel number, and then [L/OUT]. The Pro-57 now skips this channel when it is scanning. You can still select this channel manually. (See "Manually Selecting a Channel".) To disable the lockout function, select the channel, and press [L/OUT] a second time. MANUALLY SELECTING A CHANNEL If you want to listen to a single channel without scanning, press [MANUAL], then press the channel number you wish to listen to. The Pro-57 displays an "M" to indicate the manual mode. (/all-03/01/96)
