    INSTALLING STRAPS OR BUNGEE CORD The Perdix includes mounting points for either two elastic straps or two bungee cords . Both types are included in the box . STRAPS Install the elastic straps as shown in the image below . The buckles feature a locking mechanism to prevent them from inadvertently loosening .

The only difference is that the predicted time-to-surface will be shorter than the actual TTS since off-gasing is occurring slower than expected.

    Once the battery is replaced, the clock is restored to the last saved value (so it is best to remove the battery while the Perdix is on for lowest error). Quick battery changes will not require any adjustment, but the time should be corrected if the battery is removed for more than a few minutes.
