Part15 class B NOTICE:
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. 2 35GR reference manual 1. Quick reference manual conventions Operating mode Receive mode IFBW AGC ATT RF AMP MEMORY WRITE MEMORY READ SCANNING SELECT SCAN PRIORITY PROGRAM SEARCH BANK LINK SQUELCH CONFIG menu AF CLOCK & TIMER DIAL (manual tune) , Memory recall, Scanning Memory, Select scanning, Dial search, Programming search FM, AM, USB, LSB, CW, AUTO AUTO: The receiver will automatically select the appropriate receive mode, IFBW, step frequency, and others. Of course, should you wish then receive mode, IFBW, step frequency
& others may be manually changed when required. I.F. BANDWIDTH An appropriate IF filter is automatically selected when AUTO is engaged. Automatic Gain Control. In FM mode the options are AGC MID / OFF and in other modes are OFF, FAST, MID and SLOW. The 35GR features an RF stepped attenuator and preamplifier. LCD legends ATT 00 dB and AMP are used to display the settings in use. Below 30 MHz: A switchable RF preamplifier is utilized making the available selection of ON & OFF Above 1100MHz: . The attenuator is disabled to minimise signal loss through the switching unit... always set to 0dB. The AMP legend is always displayed. Storing receive data into memory. It is very convenient to store commonly used frequencies into a memory bank along with mode and attenuator status, this saves having to key the data in over and over again. Memory recall is very straightforward and quick when compared to retyping all data. During SCAN the 35GR automatically recalls each memory channel which contains data in numeric order and monitors them for activity. When an active memory channel is located
(when a signal is found and the squelch is open) the receiver will temporarily stop scanning. Memory banks may be LINKED and UNLINKED to effectively make larger or smaller groups of memories which may be scanned together. CHANNEL PASS may be used whereby memory channels can be skipped when not required (such as when permanently busy), and may be easily reinstated at a later time. SELECT SCAN enables you to make a single short list of interesting memory channels from all memory banks to be scanned as a separate function. This reduces the need to PASS, LINK and UNLINK banks and channels. Another special form of scanning is PRIORITY where a special channel is scanned for activity every interval time (1 -60 seconds). The 35GR has a SEARCH mode whereby an upper and lower frequency limit may be defined and the 35GR instructed to look for activity on all frequencies in predetermined step size in an upward or downward direction. The mode and channel step will change automatically when set to the default of AUTOMODE but data may be specified specifically if preferred. It is important that you do not confuse SEARCH and SCAN modes. Linking function of Memory banks and Search banks. The squelch control is used to eliminate unwanted background noise when monitoring a normally inactive frequency and is also used by the 35GR microprocessor to determine when a channel is active (busy). The receiver cannot scan or search when the background noise is present. The CONFIG menu is used to make many changes to operations of the receiver, the less frequently accessed items are held here to minimize the number of second function keys thereby simplifying operation. Audio Filters The 35GR is equipped with an independent real time clock with timer function. It is 24hr format displaying hours, minutes and seconds. 3 35GR reference manual Where text appears in [SQUARE BRACKETS] the keys are to pressed exactly as shown. For example : [1] [2] [0] [ENT]

Press the UP key for more than 0.6 sec Press the DOWN key for more than 0.6sec. 2. FUNC key (function key) FUNC as a legend appears when the key is pressed signifying that the receivers microprocessor is awaiting the press of another key, where the SECOND FUNCTION shown in white (not orange) adjacent to the keys will be activated... an example is to selection of the IFBW. When the second function is activated, the FUNC legend disappears and often a new LCD legend appears to confirm selection. FUNC FUNCL Use for second function. Press and hold the FUNC key for more than 0.6 sec. Use for third function When third function is activated, the FUNC legend is blinking. 3.

[UP] - if quickly pressed causes the displayed frequency in DIAL mode to be incremented in an upward direction by one step. The key may be pressed to force the scan and search onward past a busy frequency or channel it may also be used to reverse the direction of scan and search. If held for more than 0.6 seconds while in DIAL mode, DIAL search is initiated. If held for more than 0.6 seconds while in memory recall mode, the scan process will start. INCREMENT - the key will often increment sub menu options such as Audio Filters setting etc.
[DOWN] - If this key is quickly pressed, the displayed frequency in DIAL mode to be incremented in a downward direction by one step. The key may be pressed to force the scan and search onward past a busy frequency or channel it may also be used to reverse the direction of scan and search. If held for more than 0.6 seconds while in DIAL mode, a frequency search is initiated. If held for more than 0.6 second s while in memory recall mode, the scan process will start.
