4.1.2 Physical Inspection - External

INSPECT Inspect the outside of the DCP case thoroughly. Look for signs of

CASE external damage (dented, scraped, or gouged surfaces). Examine the

latches and external connectors. Describe any damage or general

deterioration noted.

RECORD If the DCP is a model 570A, step through the display, recording

DISPLAY the readings displayed for each channel.

INSPECT Open the cover on the DCP and inspect the seal between the cover

SEAL and the case. Look for loose sections of seal, tears, and worn spots.

4.1.3 Physical Inspection - Internal

NOTE POWER Note whether the power switch is "ON" or "OFF" (see Figure 4-3

for switch location).

NOTE CHANNEL Note the settings of the GOES primary channel (#1) and secondary

SETTINGS channel (#2) switches (see Figure 4-3 for switch locations). The

GOES primary channel selection switch should be set to "900"

(inhibits transmission). The GOES secondary channel selection

switch should be set to "000" (channel unused). If the switches are

not set properly, they should be reset to these channel numbers

before proceeding with this inspection.

INSPECT DCP Inspect the interior of the DCP, checking that all circuit boards are

INTERIOR firmly seated, all hold-down brackets are in place and secure, and all

cables and connectors are undamaged and in place. Describe any

improper conditions.

MEASURE Measure the internal battery voltage. If it is less than 11.8 volts,

BATTERY connect a current limited power supply set at 16 volts and 500 ma

VOLTAGE to the DCP Solar Panel/Battery Charger input for a period of 24

hours. If the battery voltage does not reach a minimum voltage of

13.8 volts, it must be replaced during servicing.

CHECK Check the installation date on the battery. If the battery is more

INSTALLATION than 5 years old, it must be replaced during servicing, regardless

DATE of the battery's state of charge.
