Possible Issues
The following phones have been tested and are in successful service in hundreds of locations, however, in circumstances where the line voltage is below the 48 volt standard, these phones may not be able to power the TEHMA Activator properly.
• AT&T 952
• AT&T 972
Other Notes:
• If your phone models include the GE 2-9450 or GE 2-9460, Due to reversed wiring in the handset manufacturing, you will require a
Version 1 TEHMA, with a regular cable; both sides set to B position, for every phone of the above models.
• AT&T 954 – Sometimes the currently shipping Version 2 TEHMA, even if set at the lowest possible setting, may still produce an audible tone that can be heard on the phone that the TEHMA has been connected to. The Version 1 TEHMA may provide greater filtering and will help to eliminate the tone in this circumstance.
In either of these cases we can supply you with the Version 1 TEHMA activator free of charge if you notify us at the time of purchase.
Issue: When a call is being transferred to voicemail from a live receptionist, the hold music is activated. When the voice mail greeting begins the hold music is not deactivated.
Solution: In order to deactivate the music, the adapter needs to hear a quick beep tone. When the adapter hears this tone at the beginning of the voice mail greeting, the hold music is deactivated. The simple fix
Download tone by Right Clicking Here, and selecting SAVE TARGET AS: while you select the folder to save this ZIP file to on your hard drive.. Instructions: Hold the phone close to desktop speaker and play tone prior to recording voice mail message.
Mute Button
• Pressing mute will block the TEHMA signal and trigger the on-hold audio. Press any key to deactivate the music for the duration of the call.
Speakerphone
• Activating the speakerphone and hanging up the handset will eliminate the TEHMA signal and trigger the on-hold audio. Press any key to deactivate the music for the duration of the call.
• When the user first takes the phone off the hook using the handset and then switches to speakerphone, the music will come on. This is normal operation. On the other hand, if you answer the phone or place a call using the speakerphone, the TEHMA tone is never recognized and if you put a call on hold from the speakerphone, the person on hold will not hear music. In this case, if you want to have music on hold, you need to hit ** hold. When you come back on line again, you need to hit any key to shut the music off. DSL
• The MOH function will not work on lines where DSL is present. Call Waiting
• The MOH function does not work with call waiting. Contact the phone service provider to deactivate the Call Waiting feature.
Cordless Phones
• For instructions on how to install a TEHMA with a cordless phone, please refer to your x500 User Manual.
• For a TEHMA to be used with a cordless phone, the user MUST USE A
HEADSET. The TEHMA receives its power via the closed voltage circuit created by installing the TEHMA along with the headset. If you install the TEHMA, without the headset, the TEHMA will not work, and possibly the handset of the cordless phone will not function properly either.
• If the user does not want to use a headset, or finds it cumbersome to have the TEHMA and headset installed on the cordless handset, the only available solution is for the user to manually trigger the on-hold message by pressing “* *” on the cordless handset’s key pad, and then pressing the Hold button.
How the x500 works:
1. When the phone comes off hook, the x500 senses this and connects that line to one of the channels in the x500.
2. It then listens to that line for presence of the 3750 Hz tone from the TEHMA.
3. If it hears this, it activates circuitry that then continuously monitors the line and listens for the 3750 Hz tone.
4. When the hold button is pressed, the handset along with the TEHMA in the handset line is disconnected from the circuit shutting of the
3750 Hz tone.
5. As soon as the tone is shut off, the circuitry in the x500 detects the 3750 Hz signal is not there and triggers a switch in the circuit to turn the music on.
6. When the line comes off hold, the handset and TEHMA is reconnected and the 3750 Hz tone is heard again, shutting off the switch and in turn removes the music from the circuit.
