Reception
Upon receiving a simple tracking stopping command, the receiving instrument should stop a tracking
process created with either of the simple tracking requests (cf. sections 4.2.1.1 and 4.2.1.2). There are
some differences in actions taken between the various Benefon/TWIG models.
Track One, Track Pro, Trackbox, TrackKeeper, Seraph, Twig Locator :
Depending on the authorization of the Control Centre which requested the stopping, the tracking
process may be stopped at once or the request may be disregarded altogether. Cf. section 2.1.3
for more information.
Esc! :
Authorization of the Control Centre which requests stopping of the tracking process is irrelevant for
purposes of this command. Only the phone number, which has been programmed to receive the
tracking reports sent by the process, is allowed to stop it. Stopping requests from other phone
numbers are always disregarded.
