[. . . ] The current setting that can be adjusted flashes on the display. Adjusting a setting Press the / rocker button to adjust the setting. By briefly pressing the / rocker button, the display jumps either forwards or backwards to the next setting. In the " CHAN", "TUNE" and "NAME" menu, the / rocker button features a "fast search" function. If you hold down a button, the display cycles continuously, allowing you to get fast and easily to your desired setting. The new setting flashes on the display until it is stored. Storing a setting Press the SET button to store the setting. "STORED" appears on the display, indicating that the setting has been stored. The display then returns to the top menu level. Exiting the operating menu Select the "EXIT" menu to exit the operating menu and to return to the standard display. When in the operating menu, briefly pressing the ON/OFF button will cancel your entry (ESC function) and return you to the standard display with the last stored settings. 18 Operating menu of the receiver SET EXIT BANK Changing the channel bank SET BANK 1 Current channel bank BANK U / : 1. . . 8, U (User Bank) SET: Stores the setting STORED CHAN Changing the channel SET 1. 01 B .

Each of the channel banks "1" to "8" has up to 20 switchable channels that are factory-preset to a receiving frequency (see "The channel bank system" on page 4). The channel bank "U" (user bank) has up to 20 switchable channels to store your selection out of 1440 receiving frequencies that are freely selectable within the preset frequency range. When switching from one channel bank to another, the channel with the lowest channel number is automatically displayed. If, during the last scan of this channel bank, an interfering frequency was detected on the channel with the lowest channel number (see "Scanning the channel banks for free channels" on page 22), the receiver display panel automatically displays the next free channel. Switching between the channels in a channel bank ­ CHAN Via the "CHAN" menu, you can switch between the different channels in a channel bank. When switching between the channels, please observe the following: Always set the transmitter and the receiver of a transmission link to the same channel. After scanning the channel banks (see "Scanning the channel banks for free channels" on page 22), only the free channels can be chosen on the receiver. Set the transmitter and the receiver to one of the free channels. Selecting the frequencies to be stored in the channel bank "U" ­ TUNE Via the "TUNE" menu, you can select the frequencies to be stored in the channel bank "U" (user bank). When you have selected one of the channel banks "1" to "8" and then select the "TUNE" menu, the receiver automatically switches to channel 01 of the channel bank "U". In this case, "U. 01" briefly appears on the display. 21 Use the / rocker button to select the desired receiving frequency. Receiving frequencies are tunable in 25-kHz steps within a switching bandwidth of 36 MHz max. For intermodulation-free frequencies, please refer to the enclosed frequency table. Scanning the channel banks for free channels ­ SCAN Before putting one or several ew 500 G2 transmission links into operation, you should scan the channel banks for free channels. [. . . ] The receiver's pilot tone function is factory-preset to "ON" (= activated). Field strength-dependent squelch Depending on the strength of the received RF signal, the receiver's audio output is opened or muted. Via the "SQELCH" menu of the receiver, the squelch threshold can be adjusted in three steps (LO, MID, HI). 29 Specifications RF characteristics Modulation Frequency ranges wideband FM 518­554, 626­662, 740­776, 786­822, 830­866 MHz 8 channel banks with up to 20 factory-preset channels each 1 channel bank with up to 20 freely selectable channels (1440 frequencies, tunable in steps of 25 kHz) 36 MHz ± 24 kHz / ± 48 kHz ± 15 ppm non diversity <2. 5 V at 52 dBArms S/ N 70 dB 70 dB 80 dB 4 steps: OFF LO: 5 dBV MID: 15 dBV HI: 25 dBV Receiving frequencies Switching bandwidth Nominal/peak deviation Frequency stability Receiver principle Sensitivity (with HDX , peak deviation) Adjacent channel rejection Intermodulation attenuation Blocking Squelch AF characteristics Noise reduction system AF frequency response S/N ratio (at 1 mV and peak deviation) THD (at nominal deviation and 1 kHz) AF output voltage (at peak deviation 1 kHzAF ) Overall unit Temperature range Power supply Power consumption Power consumption with switched-off receiver Operating time (with batteries) Operating time (with BA 2015 accupack) Dimensions [mm] Weight (incl. batteries) Sennheiser HDX 40­18, 000 Hz 115 dB(A) 0. 9 % 3. 5 mm jack socket, balanced: +17 dB u ­ 10 °C to + 55 °C 2 AA size batteries, 1. 5 V approx.
