BTR-240 Users Manual - Preliminary Page 1 of 8 Rev D – 4 / 18 / 2011 RTS Model BTR-240 Base Station Owners / Users Manual (Preliminary Information) General Description The RTS model BTR-240 base station transceiver is a rack mountable, full-duplex, wireless intercom radio. The base station provides a central relay location which handles the audio traffic between the TR-240 beltpacks. A BTR-240 base station can be used to support up to eight full-duplex wireless TR-240 beltpacks and many more for beltpacks in push-to-transmit mode. The BTR-240 uses the IEEE 802.11b technology to transmit / receive within one channel of the 1 – 11 (2.412 to 2.462 GHz) allowable channels of the 2.4 GHz ISM band. Operation of the BTR-240 is license free. The typical line-of-sight distances for the system may be 300 feet. The transmit and receive antennas are connected via unique reverse TNC connectors on the rear panel of the unit. The BTR-240 is powered via a 12 – 15 VDC receptacle on the rear panel. A 12 VDC power supply is supplied with the BTR-240. The front panel LCD display and buttons allow the following menus to be obtained: • RF operating channel • Microphone gain • Sidetone level • Transmit squelch setting • 2W / 4W intercom type settings and levels • Auxiliary In / Out settings and levels. • Speaker output setting and level. The front panel also has an on/off power control. A talk button, talk light, channel select button, channel select lights, and volume are also available for a user at the base station local headset.

BTR-240 Users Manual - Preliminary Page 4 of 8 Rev D – 4 / 18 / 2011 Operation When the BTR-240 is turned on, the backlight of the LCD and menu buttons will illuminate to indicate power. The unit takes approximately 25 seconds to boot and its status is indicated with a progress bar on the LCD. After the unit has booted successfully, the Start-up screen displays the unit model and software versions for approximately 3 seconds. The Status Screen is the main information screen of the base station. It displays the current status of the system including: • RF Channel of operation • Association (how many full-duplex beltpacks are associated with the base station) • 2W / 4W intercom settings • Auxiliary input / output settings • Speaker setting indicator Once the Status Screen is displayed, it is ready to act as an access point and TR-240 beltpacks can be turned on. Once the TR-240 beltpacks are on in “wireless” mode, they will associate with the RF channel selected at the base station. 1 Setting the RF Channel The RF channel can be changed by two different methods: • Manual RF Channel Selection • ClearScan™ NOTE: The RF channel of operation setting is remembered and the unit will continue to boot on the same channel until it is set differently by the user. NOTE: The RF channel of operation needs to be verified / set before turning on the TR-240 beltpacks. If a beltpack is already associated with a base station, it may not continue to associate once the channel is changed. If this occurs, the beltpack will need to be rebooted. 1.1 Manual RF Channel Selection To manually select an RF channel, navigate to the “RF Channel” menu item and press the <Set> button. The current RF channel will be blinking indicating that the channel is in “set” mode and ready to be changed. Using the <Up> and <Down> buttons, the RF channel is increased and decreased, respectively. Once the desired RF channel has been identified and blinking, pressing the <Set> button will select it and save the settings. Once the channel is set, the display will stop blinking and the user can either press <Set> again to re-enter “set” mode and change it, or press <Menu> to go back a menu screen. After navigating back to the Status Screen, the new current RF channel of operation is indicated.
BTR-240 Users Manual - Preliminary Page 5 of 8 Rev D – 4 / 18 / 2011 NOTE: If the <Menu> button is pressed and held for approximately half a second, the LCD will abort any current changes if in “set” mode and immediately return to the Status Screen. 1.2 ClearScan™ A user may also run a ClearScan™ from the front panel to automatically select the most available RF channel for use. A ClearScan™ is performed from by pressing the <Menu> + <Set> buttons on the front panel simultaneously for approximately 3 seconds. Once the ClearScan™ operation is initiated, the scanning status is indicated by a progress bar on the LCD. After the operation has been performed, the LCD returns to the Status Screen to indicate the current RF channel of operation. NOTE: The RF channel of operation needs to be verified / set before turning on the TR-240 beltpacks. If a beltpack is already associated with a base station, it may not continue to associate once the channel is changed. If this occurs, the beltpack will need to be rebooted. 2 Local Headset Configuration There are several ways to configure the local headset at the base station front panel. Settings for the local headset include the following: • Talk Button • Channel Select Button • Local Headset Volume • Microphone and Sidetone Levels 2.1 Talk Button Pressing the <Talk> button on the front panel will enable and disable the audio path from the headset microphone. The green talk light will be illuminated when the microphone path is enabled. The green talk light will be off when the microphone path is disabled. 2.1.1 Momentary Press and hold the <Talk> button for longer than ½ second and the microphone path will be enabled. The microphone path will be disabled when the <Talk> button is released. 2.1.2 Latch Tap the <Talk> button for less than ½ second and the microphone path latch and remain enabled. Tap the <Talk> button again to turn off the latch and disable the microphone path. 2.2 Channel Select Button Pressing the <Channel Select> button will select the intercom channel for the local headset. Each press of the button will cycle through the options; Intercom 1, Intercom 2, both. The green LEDs above the button will be illuminated for which intercom channel is currently active for the local headset. 2.3 Local Headset Volume The local headset volume can be controlled from the front panel by turning the <Volume> knob clockwise and counterclockwise to increase and decrease the volume, respectively. 2.4 Microphone and Sidetone Levels The microphone gain and sidetone level can be adjusted by navigating the menu on the LCD to the “Local Headset” option and pressing the <Set> button.
BTR-240 Users Manual - Preliminary Page 6 of 8 Rev D – 4 / 18 / 2011 Once in the “Local Headset” menu option, the “Mic Gain” and “Sidetone” levels are available for adjustment. Using the <Up> and <Down> buttons to navigate the cursor to the desired level to change. After pressing the <Set> button, the cursor and the level number will blink indicating that the base station is in “set” mode. Now, the <Up> and <Down> buttons can be used to increase and decrease the levels, respectively. Once the desired level is obtained, the setting is selected and saved by pressing the <Set> button again. Once the microphone gain or sidetone level is set, the cursor and the level number will stop blinking. At this time a user can press <Set> again to re-enter “set” mode and change levels, press <Up> or <Down> to select a different level for adjustment, or press <Menu> to go back a menu screen.
