Tel Scope™ Introduction Video
Why does the Tel Scope display “Line Voltage: 0V” while it is connected to a POTS line?
- POTS line is inactive
- Check the Tel Scope’s cordset for damage
- The wiring could be disconnected or damaged
- Check and replace batteries
Does the Tel Scope work on digital phone lines?
- No, the Tel Scope is designed to connect to an analog telephone line (POTS).
The LCD backlight turns on but there is no text.
- The batteries are not properly installed
- The batteries need to be replaced
Why does the Tel Scope appear to turn off when I press the Bell Mode button?
- Bell mode is the Tel Scope’s “off state”, if a call is received the Tel Scope will “wake up”, ring, and display caller ID information. On entering bell mode, the back light goes off immediately but the display remains on for a few seconds displaying the firmware revision.
The person on the other end of a call cannot hear me when I have the speaker on.
- The Tel Scope has a push to talk feature when the loud speaker is activated. Simply press the mute button to talk and release the button to listen.
I cannot hear the person on the other end of the line
- Use the up/left down/right buttons to adjust the volume
- There may be a load on the line or insufficient voltage
It seems that your polarity indicator is showing me incorrect results
- A typical POTS line uses negative DC current therefore the ground is considered positive and the wire transmitting DC power is negative
Does the Tel Scope detect digital signals such as DSL or T1?
- Yes, the Tel Scope will detect the digital signals and display the signal frequency. The Tel Scope will not go off hook unless the user presses F2 to connect. The Tel Scope may interrupt the data signal if the user chooses to connect.
What type of batteries does the Tel Scope require?
- The Tel Scope requires 4 AAA alkaline batteries. Using carbon batteries is not recommended.
