However, very weak radio station signals may be sup- pressed by the muting circuit. If such a very weak station is in stereo it will have a high level of background hiss. Switching to Mono Mode and disengaging the muting cir- cuit by depressing the FM Mute/High Blend button will allow the station to be heard and will cancel most or all of this background noise.

In normal operation the mute circuit is engaged, and the display indicates “FM MUTE.” Press the FM Mute/High Blend button to disengage the muting circuit and switch from stereo to mono reception. “FM MUTE” will extinguish in the display. Also, “STEREO” will extinguish if a stereo broadcast was received. Press the FM Mute/High Blend switch again to return to Auto Stereo FM operation.

In combination with the Memory button [4] a preset number can be emptied.

[4] Memory Button

The Memory button is used to store stations into the Preset Memory (1-30 Presets on FM, 1-10 Presets on AM), used in conjunction with the Down/Up [5] buttons on the front panel. When Memory is active, the Preset number flashes and the red “MEMORY” indicator is shown in the Display Panel. If no other button is pressed within 10 sec- onds “MEMORY” will stop flashing and the preamplifier will default to its previous state.

To Store a Preset:

Tune to the radio station you wish to enter into a Preset. If the station is transmitting RDS information, the RDS indicator will light up and station initials will be shown in the Display Panel. If a non-RDS station is found, then just the frequency will be shown.

To store that station as a Preset, press Memory [4]. “MEMORY” and the preset section in the display panel will start to flash. If no other button is pressed within 10 sec- onds, “MEMORY” will stop flashing and the preamplifier will default to its previous state.

Press the Down/Up [5] buttons to select which Preset number you wish to assign to the station (from 1 to 30 on FM and 1 to 10 on AM), shown as a flashing number in the Display Panel, and then press Memory [4] again. The Memory light in the Display Panel will go out and the sta- tion is now stored in your GTP-860’s memory.

To exit the Memory mode without storing a station, leave all the tuner controls untouched; the Memory mode will automatically cancel itself after 10 seconds. The Memory Presets have a memory back-up, so they will remain stored for several weeks even if the Preamplifier is switched off or unplugged from the main supply.

NOTE: You can enter a new station into an unused Preset or overwrite an existing programmed Memory Preset. By doing this you will replace the radio station previously held on that Preset number.

Deleting a stored Preset:

You can empty a Preset by deleting the stored information:

•Press Memory button [4]

•Select the Preset to be emptied by pressing the Up/ Down buttons [5].

Press FM Mute/High Blend button [3]. The Preset will then be deleted and ‘—‘ appears as the Preset number.

[5] Tuner Up/Down Buttons

The function of these buttons depends on the tuning mode selected with the Tune/Preset button [6]. The Tune/ Preset button toggles between the two operation modes:

a)Preset mode (indicated in the display area): Press the Down button to scroll to a lower number Preset; press the “ Up” button to scroll to a higher Preset number. This is a “wrap-around” function, so that going from the high- est number Preset, the tuner will go to the lowest Preset number or vice-versa when tuning either up or down.

b)Tune mode: Press the “Up” or “Down” button for more than 1/2 second to engage automatic tuning respectively up or down the frequency band. The tuner will search automatically for the first reasonably strong radio station, where it will stop. Press the Down/Up button again for 1/2 second to start searching again.

NOTE: Automatic tuning is available on both FM and AM.

By briefly tapping the Down or Up buttons you can engage manual tuning respectively down or up the frequency band for precise tuning to a specific frequency. With each suc- cessive tap of the keys, the tuner will take 0.05 MHz steps on FM so you can accurately tune into the desired fre- quency. For AM the tuning steps are factory set at 10 kHz.

This tuning mode can also be useful when trying to receive a radio station which is too weak for the auto
