ATR833S / P/N 833S-(Cxxx)-(Cxxx) Operation and Installation 2.4 Frequency Setting Frequency setting is always done by in two steps, as follows: 1. entering a new standby frequency to the desired value, and then 2. interchanging the new standby frequency and the previous active frequency by using the swap button .
ATR833S / P/N 833S-(Cxxx)-(Cxxx) Operation and Installation In order to speed up the entering of new frequencies, it is possible to configure the radio to allow entering only those frequencies that are used with 25 kHz channel width. Please refer to chapter 3.1 for information on this configuration.
ATR833S / P/N 833S-(Cxxx)-(Cxxx) Operation and Installation Respectively A push on the swap button interchanges the newly set standby frequency and the former active frequency and leaves the memory list menu. If no input is done for 10 seconds the device returns to the standard view.
ATR833S / P/N 833S-(Cxxx)-(Cxxx) Operation and Installation List entry „1“ contains the last standby frequency from the MEM menu If no input is done for 10 seconds, the device returns to the standard view. 2.4.5 Editing of the user-defined frequency list The standby frequency can be stored into any entry of the user memory.
2.4.6 ATR Frequency-Tool The ATR Frequency Tool supports the ATR833S from version 1.3. With the tool you can manage the frequency memory of the ATR833S, i.e. frequencies can be added, edited and deleted. The frequency list can be stored as a file.
ATR833S / P/N 833S-(Cxxx)-(Cxxx) Operation and Installation Range 0 - 9 The setting for the squelch depends on different factors. For motor aircraft an initial higher setting is typically appropriate, gliders may use a lower value. A lower number means higher input sensitivity. This allows...
ATR833S / P/N 833S-(Cxxx)-(Cxxx) Operation and Installation In the case of very noisy backgrounds, or use of uncompensated microphones, the automatic VOX functionality may not work adequately. In these cases, it is possible to deactivate the VOX automatics with VOX: 0 = off, and to use an external intercom-switch instead.
ATR833S / P/N 833S-(Cxxx)-(Cxxx) Operation and Installation Range 0 – 20 2.5.6 STR – Volume Sidetone Right By briefly pressing the SET button five times you get access to the STR menu. Here the volume of the sidetone for the right seat can be adjusted.
ATR833S / P/N 833S-(Cxxx)-(Cxxx) Operation and Installation 2.5.8 BRT – Brightness By pressing the SET seven times the brightness of the backlight of the LCD display can be switched on and off (or adjusted) with the VOL/SEL turn knob. Range 0 - 9 2.5.9 CON –...
ATR833S / P/N 833S-(Cxxx)-(Cxxx) Operation and Installation In order to re-enable transmission in this case, release PTT and push it again. When having more than one PTT button and microphones connected, the system can be configured (chapter 0) to use only one PTT button for transmissions.
ATR833S / P/N 833S-(Cxxx)-(Cxxx) Operation and Installation 2.8 Dual Watch Modus ATR833S comprises receiver; therefore DUAL-Watch (simultaneously monitoring two frequencies) is implemented by alternating automatically between the active and the standby frequency. With dual watch mode active, the standby frequency is tuned in, very briefly interrupted in regular intervals by the set auto-tuning to the active frequency for a fraction of a second.

ATR833S / P/N 833S-(Cxxx)-(Cxxx) Operation and Installation Quick approach: Select or enter a standby frequency which is to be additionally monitored. Set SQL with the SET button and the rotary knob to a value of at least 01.
The selection of the values is done with the VOL/SEL turn knob. 3.1 CHANNEL SPACING With this setting, the ATR833S can be configured to limit frequency selection to 25 kHz channels only. This can be used to speed up the manual frequency input in areas where no 8.33 kHz channel spacing is...
ATR833S / P/N 833S-(Cxxx)-(Cxxx) Operation and Installation 8.33 kHz: allows input of both 8.33 kHz and 25 kHz channels 25 kHz: allows input of 25 kHz channels only. A short press of SET switches to the next configuration item. Please remember to enable 8.33 kHz channel selection before flying into areas where 8.33 kHz channels are used.
