ClassCo VoiceAnnounce Caller ID 500 - Manual (Page 9)

Language Selection
The unit speaks in English and Spanish. To change the selected
language, hold down the small key and momentarily press and
release the big key. The unit announces “January” in the
selected language.
Erasing Calls
To erase the calls in the audible call log, hold down the big key
for 4-seconds. The unit beeps confirming the calls have been
erased.
Volume Control
There are four volume settings - low, medium, high, and off. To
change the volume, press and release the small key very
quickly. You may find it helpful to press the key using the
eraser-end of a pencil. The key is designed so that it is difficult
to change the setting by accident. The unit beeps reflecting the
new volume setting. It beeps twice to indicate the volume is
turned OFF.
If the volume is set to OFF, incoming calls will not be announced.
Calls reviewed while the volume is OFF will be announced at
medium volume level.
