®

• Mode indicates Grace period countdown
• Grace period – time to allow all personnel to move to a point
of safety before the voltage is allowed to be raised.
The RF signal strength should be as high as possible to avoid
communication issues (the figure is calculated on % of recent
successful messages).
For synchronised blasting it is recommended that the
communication percentage be above 75%. Communication levels
below this value could result in synchronisation failures during
blasting.
