Infrared lens … for receiving of infrared signals. Note: To avoid disturbances the IR-lens should not be covered! LC-Display The LCD (Liquid Crystal Display) is a seven-segment display (two digits) and gives information on different functions and the condition of the receiver. The following list is a key to the information that can be displayed.
SIR 320 SIR Infrared System Side- / Rear view Carrying clip, Press here to open cut-out Cut-out for lanyard Type plate Battery cover Cover screw Carrying clip There are different ways to “wear” the receiver. The built-in clip allows secure fastening to your shirt or jacket pocket. The clip is not intended using at a belt; this could obscure the lens from the IR signal. Another way is to use the lanyard wearing the receiver around your neck.
Operation Starting the receiver To start the receiver, just press one of the buttons on the navigation pad. The receiver will now display for a short time the firmware version number and then the last selected channel number. The back light of the display will high light for approx. 3 sec. and then switch automatically off to low light to conserve battery power. Channel selection is via the navigation pad, press “CH ” (to decrease) or “CH ” (to increase). The display shows the selected channel.
SIR 320 SIR Infrared System Volume control / memory function The volume control is adjusted by “VOL ” and “VOL ”. During volume adjustment a dot will appear in the top left hand corner of the display to differentiate between volume and channel selection (without dot). The minimum volume is displayed as “˙00”; maximum volume is displayed as “˙15” . The factory default setting is “˙01”. After use the receiver keeps its last settings. When used again the receiver defaults to these settings.
Disposable / rechargeable batteries The receiver was designed to meet the demands of different power supplies. It is equipped with charging contacts and charging regulators are integrated. This gives the advantage to use the receiver with disposable or rechargeable batteries (NiMH – types). Disposable batteries Type: VARTA Electric Power V8003 Size: LR03, AAA Number: 3 pcs. Rechargeable batteries Type: SANYO HR-4U Size and number as before.
SIR 320 SIR Infrared System Service mode The service mode is useful to check the receiver-settings or adjust the receiver to special parameters needed like: Check of firmware version Check of battery voltage Measurement of IR field-strength Display of factory test settings Activating/deactivating of muting Activating/deactivating of shift-mode Activation of the service mode The “CH ” and the “CH ” key must be pressed simultaneously for about 5 sec.
Battery voltage In service mode press “CH ” to check the battery voltage. The battery voltage can be read alternately with the sign “bA” and a two-digit number. The display should be interpreted as follows: voltage is e.g. “38” this equates to 3.8 Volts. Min./Max. battery voltage: Disposable batteries 3.3V – 4.5V Rechargeable batteries 3.9V – 4.
SIR 320 SIR Infrared System Guard function (option) Press “CH ” to scroll to the Guard test function “GU” can be displayed. If the Guard-module is installed and the menu item is activated it can be checked by pushing “VOL ”. The Guard signal will switch on for a period of 5 sec. You can hear a clear non continuous peeping sound. If no sound is heard either the Guard module is not installed or another problem is occurred. Pushing “VOL ” will stop the test immediately.
Exit the service mode Press “CH ” to scroll to “En” flashing alternately with “nd” in the display. At this position you can leave the Service mode by pressing the “VOL ”, “VOL ” or “CH ” key. The IR- receiver will return to the newly adjusted settings in the operation mode. The display back light illuminates and the display itself shows the version number and afterwards turns back to the starting channel.
