[. . . ] Any channels set for on-hook/off-hook voltage sensing that are not connected to a phone line will not show any recordings due to the lack of the DC voltage changes that are required to initiate a recording. If you connect any of the TeleCorder inputs to audio sources that do not have standard on-hook/offhook voltages, these channels must be set for voice activated recording (VAR). b. VAR Settings Recorder channels set for the VAR mode will detect the audio level on the channel (port) input to start a recording. It will start recording when a preset audio level is reached (normal conversation levels), and stop after the audio drops below this threshold (no sound other than weak background noise) for a preset period of time. The length of quiet required for the recording to end is called "turn-off-delay". Phone Line Recording Requirement to Start Requirement to Stop Phone Line DC voltage lower than the threshold, o/a 20v DC Phone Line DC voltage higher than the threshold, o/a 20v DC Recording from standard analog phone lines Suggested Uses Voice Activated Recording (VAR) Audio level on input is loud enough or louder than preset threshold required to start recording Audio level is lower than preset level required to continue recording for the selected turn-off-delay 1 Radio recording, broadcast or two-way 2 Meeting recording with amplified microphone 3 Audio picked up from handset or headset of analog or digital telephone set (single or multiline phone) 4 Analog phone line recording where DC voltage sensing cannot be used 5 Paging and Intercom audio User Manual -- TeleCorder with UpCorder Software -- V 2. 02-B-US 9 Parameters 1. DC Voltage Threshold: (This threshold is preset in the TeleCorder through hardware components and cannot be changed via software). 1 VAR or Off-Hook Mode for each channel 2 Threshold in 4 levels 3 Turn-off-delay/VAR space: (4, 12, 32, or 100 seconds) 4 VAR TimeOut to limit long recordings and start a new recording: (20, 40, 60, or 120 minutes) 3. Configuring Channels for Operation in VAR (Voice Activated) Mode You will use the UpCorder program in your PC to select Phone Line recording (Voltage sensing start/stop mode) or VAR mode (Voice Activated Recording), and to change and confirm these and other operating parameters. Using your PC with the UpCorder program running, select Configure from the main screen. This will open the Recorder Settings screen as shown here. User Manual -- TeleCorder with UpCorder Software -- V 2. 02-B-US 10 a. Channel/Port Setup: Each channel (also called Port) in the recorder can be set to start and stop recording using either audio activation (VAR for Voice Activated Recording) or voltage sensing. Channels showing a check mark in the boxes labeled Port 1, Port 2, Port 3, or Port 4, are set for VAR recording. Channels with no checkmark indicate they are set for phone line recording. For any channel you want to start/stop recording using the phone line voltage sensing mode, click on the box for that channel to remove the check mark, then click the Write Hardware button to confirm any changes. VAR Voltage Threshold: Set the threshold level to match the audio level on your audio source. 0: Extra Sensitive, suitable for weak audio sources with low background noise level; (for example, with weak earphone or line-out recording). 1: High Sensitivity, suitable for normal line level audio sources with low background noise levels; (normal phone handset earpiece audio or weak speaker of radio). 2: Mid Sensitivity, suitable for higher than normal audio levels and/or higher background noise levels; (for recording from a noisy phone line when voltage sensing cannot be used due to nonstandard voltages or with normal speaker audio from a radio). 3: Low Sensitivity, suitable for very high audio levels, and high background noise levels. Recording may stop if audio levels are too weak; (phone recording with non-standard and very noisy DC voltages, or extra loud radio audio). After making changes, click the button labeled Write Hardware to confirm any changes. You may be asked to un-plug and re-connect the TeleCorder USB cable to change the TeleCorder operating parameters that are set to the hardware inside of the TeleCorder. Changes to hardware settings should only be made when all channels are inactive. After settings have been changed, check to make sure all of the changes are functioning as expected. [. . . ] It is compatible with either single line RJ-11 or two line RJ-14 cables. User Manual -- TeleCorder with UpCorder Software -- V 2. 02-B-US 17 MOD-SC -- Converts Modular Phone Plug to 3. 5mm Mini-Plug The MOD-SC is used when you have a cable with a standard RJ-11 single-line telephone type plug that you need to connect to audio from equipment with 3. 5mm miniplug jack. It has an RJ-11 jack on one end and a 3. 5mm monaural mini-plug on the other end. The MOD-SC is typically used to connect modular telephone line cables used with audio recorders to the audio output of a radio receiver that uses a 3. 5mm jack for speaker or line level audio output. MTJ-S2 -- Converts a 2-Line RJ-14 Modular Telephone Jack into Separate RJ-11 Single Line Jacks This adapter/cable assembly splits a 2-line RJ-14 circuit/jack into two RJ-11 jacks (Line-1 on left and Line-2 on right). It is typically used with the two line jacks on the TeleCorder and other Voice Logging Recorders that have two inputs on a single modular jack (RJ-14, 6P4C).
