    *Time Delay: User programmable up to 23 hours, 59 minutes in one minute increments.
    *Power Source: Standard 9-Volt batteries, connected through a slide switch on the side of the case, is used to power the detector circuit and detonator. The watch operates on its internal battery.
    *Anti-Tamper Features: None
    *Watch Type: This device used a Casio F-91W, but other digital alarm watches could be utilized.
    *Size: The plastic case containing the battery and detector components measures 57 mm square x 16 mm thick (2.25" square x 0.63" thick).
