2.3.7 ALL SCAN Mode Screens
The  left  hand  screen  shows  the  radio  in  ALL  SCAN  mode  (SCAN)  for  the  marine  (MB)  channel  band. Noise rejection mode (REJ) and local mode (LOC) are selected.
The right hand screen shows the radio stopped in ALL SCAN mode (SCAN) to receive (Rx) on Channel 98  at  the  signal  strength  shown. The  radio  remains  on  this  channel  for  4  seconds  and  then  resumes scanning (unless you press SCAN to cancel the ALL SCAN mode and remain on that channel).
ALL SCAN mode Receiving in ALL SCAN mode
2.3.8 Locked Out and Unlocked Channel Screens
The left hand screen shows the radio in normal mode when a locked out channel has been selected. The X symbol appears next to the channel number to show that the channel is locked out. 
To unlock the channel, just press SKIP and the X symbol disappears (right hand screen).

2.3.9 Store Favourite Channels Screens
The  screens  show  three  favourite  channels  being  stored  on  the  marine  (MB)  channel  band;  Channel 72  is  favourite  channel  1  (CH  1),  channel  82  is  favourite  channel  2  (CH  2)  and  channel  86  is  favourite channel 3 (CH 3).
Three  favourite  channels  can  also  be  set  for  the  land  (CB)  channel  banks,  giving  a  total  of  six  stored favourite channels.

2.3.10 PSCAN Working Channel Screen
The  screen  shows  the  radio  in  PSCAN  mode,  set  to  scan  (SCAN)  one  working  channel  on  the  marine (MB) channel band while automatically checking the priority channel once every 4 seconds ( just like Dual Watch mode). Noise rejection mode (REJ) and local mode (LOC) are selected.
2.3.11 PSCAN Favourite Channel Screen
The  screen  shows  the  radio  in  PSCAN  mode,  set  to  scan  (SCAN)  favourite    channel  1  (CH  1)  on  the marine  (MB)  channel  band  while  automatically  checking  the  priority  channel  once  every  4  seconds ( just like Dual Watch mode).

Appendix B - Troubleshooting
1. The radio will not power up.  A fuse may have blown OR there is no power getting to the radio unit.
a)   Check the power cable for cuts, breaks, or squashed sections.b)   If the power cable is fine, replace the 3 Amp fuse (1 spare fuse is supplied).c)   Check the voltage of the battery that supplies the radio (see BAT in Section 2.1). It should be at least 10.8V DC.
2. The radio unit blows the fuse when the power is switched on.  The power wires may have been reversed. a)   Check  that  the  red  wire  is  connected  to  the  positive  battery  terminal,  and  the  black  wire  is connected to the negative battery terminal.
3. The speaker makes popping or whining noises when the engine is running.  Electrical noise may be interfering with the radio unit.
a)   Re-route the power cables away from the engine.b)   Add a noise suppressor to the power cable.c)   Use resistive spark plug wires and/or use an alternator whine filter.
4. No sound from the external speaker.
a)   Check that the external speaker cable is physically connected.b)   Check the soldering of the external speaker cable.
5. BAT flashes continuously and a warning beep sounds.  The power supply to the radio is too low.
a)   Press BAT to check the voltage of the battery that supplies the radio (see BAT in Section 2.1). It should be at least 10.8V DC.b)   Check the alternator on the vessel.
6. Poor reception or excessive noise interfering with the radio signal.  The radio sensitivity and noise elimination capabilities may need  adjusting.  Section 2.1 provides basic information on adjusting squelch (SQL knob), noise rejection (REJ key) and local and normal sensitivity (LOC key). However, if you continue to have problems, try the following sequence:
a)    Ensure  that  LOC  and  REJ  are  both  off  (not  shown  on  the  LCD).  Turn  SQL  to  about  halfway between the minimum and maximum settings. b)   Turn SQL slowly clockwise (right) to reduce sensitivity. If this does not solve the problem, turn SQL anticlockwise (left) to about halfway again and continue to the next step.c)  Press REJ to start noise rejection. Turn SQL slowly clockwise (right) to reduce sensitivity. If this does not solve the problem, turn SQL anticlockwise (left) to about halfway again and continue to the next step.d)   Press  LOC  to  switch  into  Local  mode  and  reduce  the  radio  sensitivity  and  range.  Turn  SQL slowly clockwise (right) to reduce sensitivity. If this does not solve the problem, the CB antenna may need to be moved for optimum performance in situations where the interference source cannot be isolated or eliminated.
7. F1 is displayed when trying to transmit.  The transmission power supply is too low or too high.
a)   Press BAT to check the battery voltage (see BAT in Section 2.1 for more information if necessary). It should be at least 10.8V DC.b)   Check the alternator on the vessel.

The  MCB  7270  radio  is  a  marine  band  (MB)  radio  that  includes  a  land  band  (CB)  capability.   The  MCB 7270 radio should be installed in a boat and operated from a boat. 
The marine band (MB) should be used to communicate with other boats and coast guard stations.  The land band (CB) should be used from the boat only to communicate with individuals or organisations based on the land. 
If you require a radio only for land-based communications, use a CB radio.
