If the radio does not have the circuitry to receive on the other freqs then it will not.
Seeing as these were built with the intent to sell for profit, I doubt that they spent the extra money on capabilities that they did not want to sell.
The VHF and UHF Bands are VERY big, most of the bands are licensed and forbidden to transmit on. Selling a radio that can use freqs that people will never legally transmit on would be a waste of money to the seller and the consumer. The 4W radios we all have technically should not make it into the country.
If you want to listen to everything your best bet would be to get a proper scanner, Uniden
makes some great ones.
For local pd/fd/amateur/business freqs you can check out http://www.radioreference.com/apps/db/?coid=2
