There are several items that may be causing speech problems
- Make sure the volume knob is turned up on the right side of the device
- Check the Edit >Speech Off option and make sure it is not checked.
- View the speech options, bring up the speech tab under the General Settings dialog (from the Edit menu, select General Settings, then review both the Speech tab and the Voice tab). Review the voice and speech settings to ensure they are correct, and be sure the volume is towards the loud setting.
- If all the settings are correct but there is still no sound, tap on File->Exit and then do a soft reset(if it is a dedicated device - just do a soft reset).
- If there is still no sound, perform a hard reset on the device.
- If the hard reset doesn't fix it, plug in the AC adapter and see if there is sound. If there is sound, then the amplifier battery probably is bad or needs replaced.Contact The Saltillo Corporation to obtain a Return Authorization number before sending the unit in(877-397-0178).
