Issue

Both of these codes result from lack of guide data

updates and are related to 920 OSDs, code 43 and

the guide displaying „to be announced‟. They can

also be associated with the conditions that result in

code 82 or 83. The box will track this lack of guide

data updates and generate a code 46 after an hour

and reboot the box after 12 hours which forces the

box to reacquire guide data at which point a code 45

will be displayed. Troubleshoot the same as

diagnostic codes 40-43.

Error codes 47 & 48 will be populated with the

[receiver name] and/or [ROUTER-„MAC Address‟] for

as many IRDs with bad connections to the network.

Start troubleshooting for the first IRD listed on error

codes 47 & 48 and rerun system test. In

troubleshooting the MRV network, verify: Green label

components BSF not used when required on STB‟s

or LNB Cabling and Connectors (including barrel and

wall); excessive use of connectors creates

attenuation and degrades the MRV network. Verify

there is nothing diplexed onto the coax – no off-air

antenna, and no CATV or MATV Splitters: every

unused output has a 75-ohm terminator (All unused

ports, including the SWiM power supply, must be

terminated); DECA‟s not used when required;

DECA‟s used on H24 / HR24 Ethernet cables

connected directly to the back of the STB Ethernet

port. A DECA BB must be installed to connect the

MRV network to the Internet.

Codes 49 and 50 are an oversubscribed SWiM

issue. Each DVR takes 2 channels and non-DVR

takes a single channel. The only workaround other

than expanding the SWiM system is for code 50

which is to put the receiver in single tuner mode via

guided setup. This will normally require an IV waiver.
