pulseEKKO PRO 9-Care and Maintenance
113
Always push in and remove the cable by holding the strain relief jacket or the plastic end connector.
Pulling on the cable will loosen the crimp and damage the cable. After connecting the fibre optic cables to
the antenna electronic boxes, loosely loop the cable and tape off some slack onto the handles (Figure 6-3).
Most breaks occur right at the cable ends when they are accidentally pulled.
These cables can stand a great deal of abrasive wear but the user should avoid sharp bends in the cable,
pulling the cable at right angles close to the fibre optics connectors, or allowing the unprotected ends to get
dirty or scratched. Erratic timezero jumps usually indicate a cracked cable (Section 7.8: P102). If
problems are encountered with the fibre optics cables, repair is very straightforward and is outlined in detail
below. The best policy is to carry spares. Short fibre optic cables are located inside each of the units (see
item K in Figure 9-1). These short cables may need cleaning and polishing from time to time.
9.6 Fibre Optics Cable Repair
The low frequency pulseEKKO PRO comes with a fibre optic repair kit (Figure 9-3).
