SEL-8310 Remote Fault Reader Operation
Operation
3.10
The POWER LED also indicates the relative battery life of the three 1.5 V (alkaline or
rechargeable) AA batteries required to power the SEL-8310, as well as any internal
RAM or Flash memory issues.
➤ A solid green LED indicates the voltage is above 3.2 Volts.
➤ A solid yellow LED indicates the voltage is at or below 3.2 Volts.
➤ A flashing red LED indicates that either the RAM or Flash memory
self-check failed. Return any units exhibiting this annunciation to the
factory for analysis.
Proper Orientation of the SEL-8310
The SEL-8310 is equipped with an integral dipole antenna. To achieve optimal range
with SEL-8300 units mounted below grade, hold the SEL-8310 so that the antenna is
on a parallel plane to the antenna of the SEL-8300, refer to Figure 3.15. If the
SEL-8300 or its remote antenna is mounted properly, the SEL-8310 should be oriented
vertically with the antenna pointing toward the sky. Because of the antenna radiation
pattern, never point the SEL-8310 directly at a manhole or directly toward the location
of the SEL-8300. Doing so will dramatically reduce the range of the radio system and
result in poor performance.

Scanning for and Retrieving Data from SEL-8300 Units
The {Scan} and {Next} buttons are located near the bottom of the SEL-8310. After the
unit is turned on and has successfully completed POST and memory tests, press the
{Scan} button to initiate a scan for SEL-8300 units within range. The Scan Initiate
annunciation, accompanied by pulsing yellow
WIRELESS INTERFACE ID LEDs, indicates
the scan sequence has begun.
