OUTDOOR ANTENNA GROUNDING If an outside antenna is connected to your tuner or tuner-preamplifier, be sure the antenna system is grounded so as to provide some protection against voltage surges and built-up static charges. Article 810 of the National Electrical Code, ANSI/NFPA No. 70-1984, provides information with respect to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna discharge unit, connection to grounding electrodes and requirements for the grounding electrode. a. Use No. 10 AWG (5.3mm2) copper, No. 8 AWG (8.4mm2) aluminium, No. 17 AWG (1.0mm2) copper-clad steel or bronze wire, or larger, as a ground wire. b. Secure antenna lead-in and ground wires to house with stand-off insulators spaced from 4-6 feet (1.22 - 1.83 m) apart. c. Mount antenna discharge unit as close as possible to where lead-in enters house. d. Use jumper wire not smaller than No.6 AWG (13.3mm2) copper, or the equivalent, when a separate antenna-grounding electrode is used. see NEC Section 810-21 (j). EXAMPLE OF ANTENNA GROUNDING AS PER NATIONAL ELECTRICAL CODE INSTRUCTIONS CONTAINED IN ARTICLE 810 - RADIO AND TELEVISION EQUIPMENT. NOTE TO CATV SYSTEM INSTALLER: This reminder is provided to call the CATV system installers attention to Article 820-40 of the National Electrical Code that provides guidelines for proper grounding and, in particular, specifies that the ground cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as practical.

By briefly tapping the or you can engage manual tuning respectively up or down the frequency band for precise tuning to a specific frequency. With each successive tap of the keys, the tuner will take 0.05 MHz steps on FM so you can accurately tune into the desired frequency. For AM the tuning steps can be 9 kHz or 10 kHz, depending on the version of your T770. This tuning mode can also be useful when trying to receive a radio station which is too weak for the auto search mode. When tuned accurately to a station, TUNED will light up in the display. With stations carrying RDS information, the stations RDS name is displayed, Program Service (PS; normally the stations calling letters, BBC R3, for instance). Refer to the separate chapter Storing, recalling and naming Presets for more information. NOTE:The 120V versions (North America) do not have RDS (Radio Data System). 16. FM MUTE/MODE This button combines two functions; it switches the tuner from Stereo to Mono and disengages the muting circuitry at the same time. The muting circuit will mute the tuner in between radio stations when searching or tuning. This way the tuning noise is avoided. Very weak radio station signals however may be suppressed 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 circuit by depressing the FM MUTE/MODE 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, the display indicates FM MUTE. Press the FM Mute/Mode 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/Mode switch again to return to Auto Stereo FM operation. SURROUND FUNCTIONS 17. EXT. 5.1CH Selects the multi-channel output signal from the DVD player or external decoder source (such as DTS, MPEG, etc.) connected to the EXT. 5.1 CH input as the active input. NOTES:The Speakers B (No. 3), Digital Audio Selector (No. 18) and Surround mode (No. 19) buttons do not have any effect in this mode. No audio signal is available from the Tape 1, Tape 2, Video 1 and Video 2 outputs when the EXT. 5.1 CH input has been selected. 18. DIGITAL AUDIO SELECTOR With the Digital Audio selector button you can assign which one of the Input Selectors will be linked to either the Digital Audio 1, Digital Audio 2 or Digital Audio 3 inputs. When a Digital Audio input is linked to one of the Input selectors, whenever a digital source is sensed at the Digital Audio input, the Digital Audio input will be used instead of the corresponding analogue audio input. To assign a Digital Audio input to a specific Input Selector button: -Press the desired input button (except AM, FM, Tape 2 Monitor and EXT. 5.1 CH.) -Press the Digital Audio Selector button. The "DIGITAL AUDIO" box will light up in the display with the first available digital input. -Press the Digital Audio Selector button again to until the desired digital input lights up (either 1,2 or 3). Digital Input 1 is the optical input; Digital Audio input 2 and Digital Audio input 3 are the coaxial inputs.The next time this input is selected, the chosen Digital Audio input will automatically be selected as well. NOTES:It is not possible to select a digital input if Digital Audio input 1, Digital Audio input 2 and Digital Audio input 3 have already been assigned. You must first de-select the desired Digital Audio input from the Input Selector button it has been assigned to. TO DE-SELECT A DIGITAL AUDIO INPUT -Select the input to which the Digital Audio Input is assigned (the display indicates which Digital Audio Input is assigned to the selected input). -Press the Digital Audio Selector until the Digital Audio extinguishes in the display. The Digital Audio input has now been de-selected from the chosen input. When no digital source is available (not connected or source is switched off) the associated Digital Audio input number will blink. Once a digital signal is available and the input has locked on to the digital signal it will remain lit. 19. SURROUND MODE With the Surround Mode and buttons the available surround sound modes can be selected. The selected Surround mode is permanently indicated in the display area and is also shown for 3 seconds in the large alphanumeric section of the display. The Surround Mode buttons scroll through the available surround sound modes: Surround Mode Off Dolby Pro Logic EARS Surround mode Off, etc. With Dolby Digital surround sources Dolby Pro Logic and EARS are not available: Surround Mode Off Dolby Digital. If Dolby Pro Logic or EARS is selected the T770 will automatically switch to Dolby Digital. Dolby Digital has six independent channels available in total: Left, Center, Right, Surround left, Surround Right and an Effects Channel (Subwoofer). Dolby Digital is only available as a Surround Mode if the source is Dolby Digital and a Digital Audio input is used. The Dolby Digital signal conforms to Dolbys AC-3 standard, which allows for several channel configurations. The channel configuration is shown the display together with the input selected. For example, with regular Dolby Digital sources the display will show ch3/2, indicating that there are 3 front channels and 2 surround channels available. Dolby Pro Logic decodes the center and surround sound signals embedded in stereo movie sound tracks from e.g. video, Laser Disc or TV. To decode correctly, the source must be a Dolby Surround or Dolby Stereo soundtrack. GB 13
