You cannot delete all telememo records at once, only one by one.
To delete, scroll to the record you need to delete, press the upper left button until the cursor flashes. Then press the lower left and right buttons at once until "CLR" is displayed.
A simplified manual of module 2515 is here
If you need to delete all records, you'll need to hard-reset the watch. Simply by removing the battery power may not work, especially on Databank models that use EEPROM. I'm not sure if the this module uses EEPROM for telememo.
If you need further assistance, contact Javys.
