The proper installation of the radar equipment is critical in ensuing its effective and reliable performance as 
well as facilitating maintenance and repair.    Therefore, carefully install the radar equipment by following the 
procedures below: 
 
1)  Install the scanner as high as possible while ta
king the scanner's weight into consideration. 
 
2)  It is preferable to install the display unit in
 t
he wheel house to facilitate observations. 
 
3)  The standard cable length for installing the radar JMA-5300MK2 is as shown in the table below.    If 
th
ere is a n
eed for using a cable longer than the standard length, notify JRC of it beforehand.    A 
cable longer than the standard length may hider performance of the radar, so give it careful 
consideration when planning the installation.    (The standard cable length is considered to be 
sufficient for small and middle size ships for which this radar is designed.) 
 
 
  Standard cable length (number of cores) 
JMA-5312-6/6HS  20 m (19 cores) 
JMA-5322-7/9/6HS  20 m (19 cores) 
JMA-5332-12  10 m (19 cores)(between the Display Unit and the Junction Unit) 
20 m (14 cores)(between the Junction Unit and the Scanner Unit)
