Our 2019 R23 was delivered yesterday. So much to learn!
First question -

Can i power up the electronics so i can learn my way around while the boat is on the trailer? I can get shower power to it from the house. Do i need to pull any fuses for the engine or any other equipment if i have the key on for an extended period of time?
 
You should not run your sonar if not in water. Open your Garmin manual, or download one for your unit, and see how to do that while getting acquainted with other features of your boat.
 
Congratulations Randy! Have fun exploring the boat!
 
Congratulations! You can use the Garmin but not the sonar or probably the radar while on the trailer. You don’t have to have the key on. All you need is to have the HOUSE bank switch on. If you hook up to shore power turn on the battery charger and this will keep your batteries charged while you “play”. You can learn a lot without being in the water. Look around and explore all the nooks and crannies of this boat. It truly is a great boat.
 
Hold the on button for a second on the chart plotter and it will give you a quick option to turn off the sonar.

I turned off the sonar and learned a lot about my Garmin and the radar on the hard. Remember that radar should not be on if there are people close. For example when docking etc.
 
“At present, there is no substantive evidence that adverse health effects, including cancer, can occur in people exposed to RF levels at or below the limits set by international standards. However, more research is needed to fill certain gaps in knowledge.” (WHO)

“ Electric and magnetic fields are complex physical agents whose potential health effects are the subject of much research. Particularly controversial are the biophysical mechanisms by which these RF fields may affect biological systems. General health effects reviews explore possible carcinogenic, reproductive and neurological effects. Health effects by exposure source are noted in radar traffic devices, wireless communications with cellular phones, radio transmission (radar) and magnetic resonance imaging (MRI).” (OSHA)

However; I do not want to add to the data base. RADAR uses pulsed low power in the microwave range. This energy does penetrate body tissue. Yes, I’ll admit it is very slight, but again, I would rather avoid this. Please do not irradiate me as you approach the dock.

But am I irradiating myself every time I turn on my radar? I'm only sitting about 10 feet behind it.

Interesting. I'll have to look into this. Thanks.

From Garmin radar user manual.

Minimum Safe Operating Distance
When it is transmitting, the radar should be located in a position
on the vessel that is at least this far from people. IEC 60936-1,
clause 3-27.1, specifies the maximum distances from the
antenna at which radio frequency (RF) levels can be expected.
These minimum safe distances apply for a transmitting radar
with a rotating antenna, and are much larger when the antenna
is not rotating. If rotation of the antenna is obstructed for any
reason, the transmitter will automatically turn off.

100 W/m² 50 W/m² 10 W/m²

GMR 18 xHD/18 HD+
0.08 m (3.15 in.) 0.11 m (4.33 in.) 0.25 m (9.84 in.)

GMR 24 xHD 0.08 m (3.15 in.) 0.11 m (4.33 in.) 0.24 m (9.45 in.)

Yes, but VERY little. Most of the energy emitted is concentrated in the focused radar “beam”. Hopefully most of that is projected out above your head. I do not set in the command bridge with the radar transmitting.
